Lifestyle Choices for Maximizing Health and Lifespan

Unless you have been living under a rock on an isolated island, I am sure you have heard that lifestyle choices have big impact on both your health and how long you live.

Living longer means not dying sooner.  And, to not die sooner, you must take actions that eliminate the various ways one dies.

Living healthy, means taking actions to prevent all the ways one loses their abilities to enjoy day-to-day activities of life. Or, at least postpone the time as far into the future as possible before developing disabilities.

In both case, i.e., living longer and living healthy, lifestyle choices play crucial roles. But what are these life choices, besides the ones you hear all the time:  Eat Better and Exercise.

When I started to systematically pursue this topic of living optimal lifespan possible (my goal being 120 years), with optimal health span (my goal being no disabilities), I started enumerating all areas of life in which one can take some action to make this impact.

Of course, not everything is in our control. We did not come to this earth with guarantees. Unforeseen, random event, or events that are not in our control can ruin all our goals and plans. But the objective is to not let the possibility of events not in our control prevent us from taking actions that are indeed in our control.

So, here are all 13 dimensions of lifestyle that I have discovered so far that impact health span and life span. Each subject is a very extensive topic by itself.  I just very briefly summarize my personal take on these and may be an example of how I am attempting to address them in my lifestyle and where you can read about further in these blog posts.

1. Benchmarking Health: Knowing where you are is where I believe it has to all start. You go to doctor’s office and they take your physical measurements (height, weight), you vitals (pulse, blood pressure), order some measurements from the lab and then compare those with what should be “normal” for you. In Post #7 – Can biomarkers help in the quest for vitality and longevity?, I discuss the various measurements you can use as biomarkers for health. These days I measure:

Daily: Weight, waist, fat near navel and thigh, BP, SPO2, pulse, my over-all subjective state of my physical, emotional and mental health

Weekly: pH, Nitric Oxide, fasting glucose

Quarterly: Bloodwork through my primary physician – CBC (complete blood count), typical chemistry panel, Lipids (Cholesterol total, HDL, LDL, VLDL, Triglysrides), TSH, T3, T4 (Thyroid hormones), Male Hormones (Total and Free Testosterone, Estrogen, LH, FSH), Hydroxy-D, fasting glucose, A1c, PSA (for prostrate tumor screening), CRP, (for inflammation), Homocysteine (for heart condition)

Annually or Biennially: Telomere Measurements (DNA strands that dictate how long cells live), X-Rays of joints if I suspect arthritis etc., Ultrasound Study of Carotid and Aorta arteries, MRI’s to detect any tumors, eye-exam, hearing test, EKG.

Every 5 years: Colonoscopy, Stress-test.    

2.  Nutrition – That is everything that crosses our lips, what we eat or drink. I discussed the topic of nutrition in a series of eight blog posts on this subject of Optimal Nutrition, Posts #22 through #29.  additionally, Post #15, #31 and #32 discuss the topic of how and when to complement the nutrition with supplements.

 3. Exercise – Exercise is indispensable for building and maintaining muscle strength, flexibility, balance, endurance. There is also abundant proof that it helps with the metabolism, overall health and health of specific organs. I discussed this topic of exercise in blog post #30 – How much and what type of exercise do you need for optimal health?

 4. Maintaining Musco-skelatal Integrity: Pains in the back, knees, hips, shoulder, wrists and other various joints creep up. We may think that these pains just come out of nowhere. After all, we often notice that “yesterday it did not hurt and today it hurts”. So, it got be a random event. Right?

Reality is that unless there was a trauma caused by an accident, most of these are the result of repetitive movement in un-aligned joints. The underlying cause could be neglect of the muscles, ligaments and tendons surrounding joints or prolonged asymmetrical movements, e.g., always carrying a bag on the same shoulder, or playing games such tennis or golf that inherently require asymmetrical movement.

Yoga, myofascial massages, Rolfing, rolling with foam rollers, visiting a chiropractor for body alignment, weight bearing exercises for join strengths, e-cise routines designed by Pete Egoscue are methods I have learned for maintaining musco-skeletal integrity.  I discuss some of these in Post #30 – How much and what type of exercise do you need for optimal health? And Post #49 – What is the role of massage therapy in Optimal Health? Also, I discuss how you can use foam rolling for body alignment in Post #39 – Ever heard of foam rolling.

5. Maintaining Optimal Dental Health: Good dental health not only impacts quality of your life, it can also impact how long you live.

The American Heart Association published a Statement in April 2012 supporting an association between gum disease and heart disease. The article noted that current scientific data do not indicate if regular brushing and flossing or treatment of gum disease will decrease the incidence, rate or severity of the narrowing of the arteries (called atherosclerosis) that can lead to heart attacks and strokes. However, many studies show an as-yet-unexplained association between gum disease and several serious health conditions, including heart disease, even after adjusting for common risk factors.

You may also have seen health and lifestyle surveys used for estimating life-expectancy that want to know if you floss daily. If you do the models give you credit for an extra 2 to 4 years of life.

In Post #47 – What does optimal dental health look like and how to achieve it?, I discuss this topic in greater detail.

 6. Maintaining Mind-body Connection: Our mind and body are inherently connected. Maintaining the connection between the two is essential for optimal health. Yoga, Tai Chi, Qigong, are some ways to develop and maintain mind-body connection.  I have very limited experience with Tai Chi and Qigong. I do, however, perform Yoga as part of my lifestyle.  In Post #11 – My first year of experience with Bikram Yoga, Post #12 – My second year of experience with Bikram Yoga, I describe how I incorporated Bikram Yoga into my lifestyle.

 7. Enhancing and Maintaining Brain: If we lose vitality of the brain, the quality of life suffers dramatically. Alzheimer and other forms of Dementia can often be very painful way of living. Evidence is mounting that for optimal brain health, we must keep the brain stimulated with right activities. All my life, I have been very focused on left brain type of activities. As I was turning 60, I decided to do something about it and started taking piano lessons to stimulate my right brain and prevent any premature aging of the brain. I discuss the activities for maintaining optimal health in Post #57 – Optimal Mental Health – what is it and how to achieve it?

 8. Stress Management: Stress is a root cause of many diseases. We have all experienced how stress can bring about disturbances in the digestive systems, back pain, high blood pressures, even heart attacks and strokes. Yoga and Meditation are two of the ways to manage stress. Perspective management is another powerful method. I got initiated in Transcendental Meditation over 30 years ago and I have been doing TM ever since with good benefits. I tackle the subject in Post #16 – What is stress really and why is it bad for longevity and health and Post #17 – Is meditation an effective antidote to stress.

9. Adequate Sleep: There is more and more evidence every day that inadequate sleep can cause all sorts of ailments. 7 to 9 hours of restful sleep is considered optimal. All my life, I thought the object of the game was to get away with as little a sleep as possible. Sleeping more than 6 hours every night is still a challenge for me. Although I am working on it to extend sleeping hours during the week and may be do some catch up sleeping during the weekends. Maybe I will tackle this topic in a future post. In Post #61 – How much sleep do we need? – I discuss the latest in sleep research.

10. Social Engagement: World-wide Study of Blue Zones, i.e., geographical areas where longest living people are clustered, showed a very surprising factor that contributed to long healthy life of people living there. Researchers found that people in Blue Zones are socially very engaged. Centenarians in these areas are engaged with tight knit groups of friends and family. So, the conclusion is that social engagement is an important factor in living longer and healthier.

 11. Purposeful Living: It is well known that death rates spike after the holidays and after major life events. Researchers deduce from studies of such phenomena that people live only as long as they find life meaningful.

Of course, it needs an ongoing effort to figure out what one can derive meaning from. One may find meaning in raising kids or grand kids, contributions to society, being the best spouse one can be or from “slaying some dragon”. Some people find meaning in their faith and service to God. Others find meaning in being of service to mankind or their fellow human beings. Yet others can find meaning in their job or career.

Viktor Frankel in his book: Man’s Search for Meaning, explores this topic beautifully. 

12. Make Full-use of All Modalities of Medical Care: Modern medicine has developed amazing and miraculous treatments. By making use of the modern medicine one can live much healthier and much longer.  In general, the earlier you are able to catch a disease and the sooner you start treatment, better your chances are of a cure or at least minimizing the damage. Mantra for modern medicine is “early detection, early cure”

 Alternative schools of medicine, such as Ayurvedic, Homeopathy, Aquapuncture, Naturopathy, offer valid means for preventative care and whole-person healing.  Leveraging these modalities of medical care as appropriate can offer means for optimal healing and living. Here the rule is the age old wisdom: An ounce of prevention is better than a pound of cure.

I was even able to eliminate my severe seasonal allergies by working with doctors of Naturopathy and thus was able to totally change the vector of my health as I discuss in Post #8 – So, did I you tell you the story of my allergies. Also strengthening your immune system can have major consequences on how your body deals with diseases as I discuss in a series of Posts #51 – 54 – How to Optimize Your Immune System – Part I through Part IV

13. Making use of Genetics Science: There is of course the truth of genetics. Genes do play a role in how long we will live and what diseases we may have the tendencies to develop. Over the last few years, however, scientists are finding that inherited genes often do not determine your destiny, it is the lifestyle that can either turn those genes on or off. This is the exciting field of epigenetics.

 Studies from the filed of epigenetics do  give us opportunities to leverage genes.  Through genome mapping, we can find out what might be our tendencies and to what aspects of our life, therefore, we should pay particular attention. Over the last few years, I have gotten my telomeres measured – these are tips at the ends of genes that are considered to act like our lifespan clocks.  I discussed this in Post #50 – How to optimize your health by maximizing your telomeres. More recently, I have sent for genetic testing to be able to receive personalized genetics bases lifestyle coaching. I will share results of that experiences in a future post.

The percent of role of genes that we cannot do anything about is constantly shrinking all the time. Now it is believed that only between 5% to 15% of lifespan and health span is determined by genes that we have no control over.

Bottomline:

In summary, researchers have shown again and again that health span and life span depend upon one’s lifestyle choices. A holistic look at lifestyle choices means many different and distinct areas of life.

I shared my take on these dimension of lifestyle and some of my experience. Also, gave references to where you can find more information, whenever, I have already discussed that topic in more detail in my blog posts.

  1. Benchmarking Health
  2. Nutrition
  3. Exercise
  4. Maintaining Musco-skelatal Integrity

Post #50 – How to optimize your health by maximizing your telomeres?

What in the world is Telomeres? – you say

Well, if you have not heard of the word Telomeres, I will explain it here, since it is likely that you will be hearing about it more and more.  Especially, if you are interested in optimal health, living long and living health.

So, first here are some useful terms.

What is Telomere?

Telomeres are disposable buffers at the ends of chromosomes which are truncated during cell division. Their presence protects the genes before them on the chromosome from being truncated. During the process of each cell division, the telomere ends become shorter.

Hayflick Limit

An American scientist Leonard Hayflick established limits to cell replication what is now called Haflick Limit. The Hayflick limit is the number of times a normal human cell population will divide until cell division stops. Empirical evidence shows that the telomeres associated with each cell’s DNA will get slightly shorter with each new cell division until they shorten to a critical length.

Most cells will divide between 50 to 70 times before they cannot divide any more.

Role of Telomeres in Cellular Aging

As Hayflick first demonstrated, human cells have an inborn “counting mechanism” that tells them when to senesce, or stop dividing: Each time a cell replicates, the ends of each chromosome, i.e., telomeres, get shorter, and once the telomeres get too short, they trigger a “senescence program” that arrests the cell’s growth.

In short, telomeres represent body’s clock that determines our life-span and our health span.

Telomerase to the Rescue!

Telomerase is an enzyme that adds length back to the end of telomeres.  In a simple leap of logic, you can quickly figure that telomerase enzyme is an antidote to shortening of the telomeres.

As you can also guess things are probably not that simple.  They never are when it comes to human biology. But for this brief blog post, I will keep it simple.

So, with this premise of telomeres determining when cells say “uncle”.  And, Telomerase offering an antidote, race is on for researchers and entrepreneurs on many fronts.  Numerous questions are being asked and some have even been answered:

  • How do you measure telomeres inexpensively?
  • Do telomeres really correlate with one’s biological age?
  • Does telomere length account for life styles that have been known to determine one’s health span and lifespan?
  • What factors stimulate telomerase activity? Can we measure that?
  • What about the role of telomerase in cancer, where cell replication goes on without any limit?
  • And, so on and so on..

Some hard answers have emerged, well-rooted in hard science.  On the other hand, other answers are preliminary and people are making wild leaps of logic to get to the market first with commercial products and services.

Measuring Telomeres

Several companies now offer services to measure telomeres. For example, Titanovo, Inc., SpectraCell Laboratories, Telome Health, Inc.,  Telome Home.  Basically, you send them blood or swab and they will  send you your telomere measurements.

My experience

I recently got my telomeres measured by Titanovo, Inc.

I signed up online. They sent me a kit.  I swabbed inside of my cheeks and mailed it back.  I also filled in a lifestyle survey on their website they use to correlate the results with lifestyle.

Few weeks later, they posted my results on their website.  The following pictures represent result I received.  (You can click on these to enlarge and make them readable)

Titanovo profile 3-2016_Page_1

Titanovo profile 3-2016_Page_2

What do my results mean?

Here is my take away.  My relative telomere length is 0.62, which if you interpolate on one of the charts that means my telomere corresponds to a 48 year old male. 13 year younger biologically sound pretty good to me!

I reported my diet as vegetarian.  If I were to change my diet to vegan, according to the last chart, my telomere length could be 0.67. That represents an additional opportunity for 8% advantage in terms of biological age.  8% increase in lifestyle is pretty significant to me.

Since I just started experimenting with a vegan diet about 3 week ago, I will be interested in retesting the telomere length in a year to see if the results correspond to what Titanovo is forecasting.

Titanovo sells bundles of multiple kits, so people can play with their lifestyles choices and then see the impact, in say 3 months at a time.

Bottom Line

  • This area of telomere and measuring impact of lifestyle choices through measuring telomere is quite exciting.
  • A lot of research is going on in both gaining fundamental understanding as well designing interventions that could potentially defeat body’s lifespan clock.
  • Sound like pretty cool stuff to me, if this works as advertised.
  • I bet we will be hearing a lot about this topic, so stay tuned.

What is your perspective of this topic?

Post #41 – So, how to measure how close to optimal is your health? Or, how quickly are you aging?

“How old are you?” someone asks. Number of years since birth is the generally the answer – that is your Chronological Age or CA.

But how hold do you feel? How old do you act? How old do you look? That is your Biological Age or BA.

Wouldn’t it be nice to actually be able to measure your biological age?

CA and BA is the difference between being 40 year old and going on 60. Or, may be being 60 year old and going on 40.

Wouldn’t it be more useful to have a single number like BA, than understanding individual factors like your total cholesterol, HDL, A1c, VO2 Max, etc?

Recently, in the media there has been a buzz about a recent research published by scientists led by Duke University School of Medicine about measuring biological age. For example, see the article in WSJ: How Quickly Are You Growing Old?

Now there are a quite a few websites, where you answer a bunch of question and they will tell you, your biological age as compared to your chronological age.

For example, here are three such sites, I tried (my CA is 60.9 years):

http://www.biological-age.com/ calculated my biological age as 36

https://www.sharecare.com told me my BA was 53.6.

http://www.growyouthful.com/gettestinfo.php said my BA was 46.

Each of the sites followed up with advice and helpful hints on what I could start or stop doing to further increase my expected health and lifespan.

Unfortunately, none of these websites show exactly what they do with the information you provide and how they arrive at the number they call Biological Age.

But this recent study, “Quantification of biological aging in young adults”, by Daniel W. Belsky et al, is very rigorous treatment of this subject and gives you all the details behind the curtain. And, for me, these details are not only fascinating but actually quite useful to understand what matters for biological age to start diverging from chronological age. In other words, what slows down or speed up aging.

The study calculated the aging rate of 954 men and women—taking various measurements of their bodies’ health—when they were each 26, 32 and 38 in chronological years. By analyzing how these measures changed over time, the researchers were able to see who aged faster and who slower than normal.

To measure the pace of biological aging, which the study defined as the declining integrity of multiple organ systems, the researchers relied on 18 separate biomarkers, summarized in figure below.

These ranged from common measures such as HDL-cholesterol levels and mean arterial blood pressure to more obscure ones like the length of telomeres—the protective caps on the ends of chromosomes that shorten with age.

Go on in Years

Chronological age of all participants was 38 years. However, researchers found that the biological ages varied from 26 years to 60 years.

For measuring how fast people aged, they calculated aging over 12 years. About 30 percent aged biologically one year for every calendar year. There were those who aged as much as 3 years for every calendar year. And, there were four members of the group who aged not at all or actually got biologically younger during the 12 year period.

BOTTOMLINE:

Finding one’s Biological Age is a fascinating concept and can be very useful in optimizing health and life span. However, this is not an exact science just yet, although good strides are being made in research.

However, if you want to focus on living optimally, you can focus on changing your lifestyle to optimize the basic 18 or so biomarkers used in this study. Most of these can be impacted by lifestyle choices. Only 20% depend upon genetics.

Proper food, hydration, exercise, supplements and medical care are the key methods to managing these primary biomarkers.

Websites that compute biological ages also suggest additional actionable items that seem to strongly correlate to optimal health span and life span. These include:

  1. Optimal sleep (7 to 9 hours)
  2. Reduced stress (meditation, perspective management)
  3. Reduced exposure to toxins (organic food, reduced use of chemicals, clean water)
  4. Increased social contact (having friends, family, living with a life partner)
  5. Purposeful living (satisfying work, hobbies, social endeavors)

What is your take on this subject?

Post #16 – What is stress really and why is it bad for longevity and health?

22 Sunday Jun 2014

Stress has become such a common buzz word. We all talk about it. We generally know it is bad for us. It is constantly in the news.

There are exceptions though. Some believe that stress is good, arguing that if you take away the stress you take away the motivation and drive.

But whenever I get into conversation with someone and start to dig a little deeper with questions like, “So, what do you think is stress?” “Why do you think that stress is bad?” Why do you think it is good?” Or, “How do you deal with stress?” The subject becomes very squishy, very quickly.

Even Hans Selye, the person who originally coined the term stress in 1936 in the context of health and spent life-time studying it, at one time threw up his hands and declared, “Everyone knows what stress is, but no one really knows.”

So, let us take the first question first, what is stress, any ways.

Webster’s Dictionary defines Stress as “a state of mental or worry caused by problems in your life, work, etc.”; or, “something that causes strong feelings of worry or anxiety”

According to the American Institute of Stress, another popular definition of stress is, “a condition or feeling experienced when a person perceives that demands exceed the personal and social resources the individual is able to mobilize.”

Few useful concepts, while talking about stress are:

Acute Stress: Fight or flight. The body prepares to defend itself. It takes about 90 minutes for the metabolism to return to normal when the response is over.

Chronic Stress: The cost of daily living: bills, kids, jobs…This is the stress we tend to ignore or push down. Left uncontrolled this stress affects our health- our body and our immune system. This is the type of stress that causes wear and tear on our bodies and can impact health and longevity.

Eustress: “Good stress” in daily life that has positive connotations, e.g., marriage, promotion, child birth, winning money, new friends, graduation

Distress: “Bad stress” in daily life that has negative connotations, e.g., divorce, punishment, injury, negative feelings, financial problems, work difficulties.

So, from  the point of view of theses definitions, the stress is really a subjective concept, based on how we perceive a thing or an event. The same event or activity, say a roller coaster ride, could be a eustress (good stress) for one person and distress for another. This is why psychologists or mental health practitioners often get involved in diagnosing and helping cope with chronic stress.

Although stress is a subjective concept, the impact on our bodies is often very objective and real. We have all experienced the rising of hairs on the back of the neck, the sweats, tension in our gut, racing of heart, dilating of pupils, and pumping of blood in our face, arms and legs.

As the following figure shows, stress starting in mind, causes, a chain reaction of neurological, chemical and biological processes. (Figure is taken from a presentation,Why Stress Is A Far More Important Cause Of Coronary Disease Than Cholesterol, by Paul J. Rosch, M.D., F.A.C.P. President, The American Institute of Stress)

Effects of Stress

Physiological effects of most acute stress events subside about 90 minutes after the conclusion of the stress event. Body returns to normal homeostasis or biological equilibrium.

However, it is the repeated acute stress events or chronic stress that are real cause for concern and take toll on our bodies. The results of such chronic stress can be objectively measured from a host of biomarkers that include (from Biomarkers of Chronic Stress, by Laalithya Konduru):

  • Metabolic Biomarkers: Cholesterol, Albumin, Waist-to-Hip Ratio, Glycosylated Hemoglobin
  • Immunological Biomarkers: IL-6, TNF-α, CRP, IGF-1
  • Neuroendocrine Biomarkers: Cortisol, DHEA, Adrenaline, Noradrenaline, Dopamine, Aldosterone
  • Certain Metabolites, chemical figure prints of cellular processes
  • Modifications in Mitochondria
  • Induction in the Brain of DRR1, a tumor suppressor gene

Most of us recognize some of these biomarkers. Others are quite esoteric. In any case, from this list, it does not take a neuroscientist to figure out that chronic stress can mess with a number of things that are key to our health: insulin, cholesterol, hormones, our immune system, can cause inflammation, reduce energy level in the body and impact working of our brain.

Looks like a real important subject to me, if we want to live healthy life free of chronic diseases for an optimal life span.

What do you think? How do you fee about stress?

In a future post, I would like to explore some anti-dotes to chronic stress

Post #7 – Can biomarkers help in the quest for vitality and longevity?

How do we die and how do we lose vitality questions so far have focused my attention on the hurdles to overcome. Some of these have to do with challenges that shorten or bring end to our lifespan. Other items are “diseases” that can decrease our vitality and vigor.

All of these items are, of course, important. For the moment, however, let me step away from these hurdles and reframe the questions.

Let us say, I don’t really have any disease, but I want to live a lifestyle to achieve the optimal health and lifespan. How can I objectively assess where I am presently and then either maintain or improve from here? In other words, how to pursue living an optimal health and vitality, not merely trying to be disease free?

Study of Biomarkers has been an area of aggressive research and pursuit in vitality and aging since the 1980’s.

Biomarkers (short for biological markers) are biological measures of a biological state. By definition, a biomarker is a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes or pharmacological responses to a therapeutic intervention.

In the context of aging, an important focus for biomarkers has been on finding “the clock” that potentially ticks away our lifespan. Discovery of telomere as a potentially genetic clock is one example of a biomarker that won Elizabeth Blackburn of the University of California San Francisco a Nobel Prize. More recently, Steve Horvath of UCLA has introduced another important biomarker to measure human aging through epigenetic signatures.

Both of these works have sparked fascinating research into areas of aging and extending lifespans. I would like to explore these topics in future blog posts.

On the other hand, for vitality, William Evans, PhD, and Irwin H. Rosenberg, MD, professors of nutrition and medicine, respectively, at Tufts University introduced a concept of biomarkers back in 1991 through their book Biomarkers (Simon and Schuster, 1991), updated in their book, BIOMARKERS: The 10 Keys to Prolonged Vitality (Simon and Schuster, 1992) and more recently updated in the Tufts University Health and Nutrition Letter.

In these publications, Evans and Rosenberg isolated the following signposts of vitality that can be altered for the better by changes in lifestyle:

  1. Muscle Mass
  2. Strength
  3. Basal Metabolic Rate
  4. Body Fat Percentage
  5. Aerobic Capacity
  6. Blood-sugar Tolerance
  7. Cholesterol/HDL Ratio
  8. Blood Pressure
  9. Bone density
  10. Ability to regulate Internal Temperature

These same 10 biomarkers keep showing up everywhere in preventative care, in strength training, in other training programs, in nutrition/diet plans and so on.

Additionally, other important biomarkers I have seen show up in various medical and scientific literature and studies on health, vitality and longevity are:

  1. Stress
  2. Inflammation
  3. Sleep
  4. Body’s pH
  5. Flexibility
  6. Balance
  7. Musculoskeletal alignment
  8. Physical and mental reaction time

So, the way I see it is this: the goal of achieving optimal health and lifespan should focus on developing lifestyle that optimizes these objectively measureable / observable biomarkers.

Any exercise plan, nutrition plan, lifestyle adaptations, and any medical program for achieving optimal vitality and lifespan thus must be measured against these criteria.

What do you think?

Do you know of other biomarkers that we can impact that are important for attaining optimal vitality and lifespan?

Post #5 – Why do I want to live to 120?

As I start this conversation of purposely living to 120, I usually get a wide variety of reaction from people. Frankly, the one that took me by surprise the first time I heard, and, to some extent, still does is, “Why would you want to live to 120 even if you could?”

Now, I have to admit, before I started to get into such conversations, I just naively assumed that most people wanted to live as long as possible. After all, just look at the heroic efforts doctors, hospitals and patients put up to extend life just by few years, months and often even days.

When I was discussing this topic with my father-in-law recently, he remarked, “I will be happy to die at 90.” Then he quickly calculated and figured out that that was only 13 years away. So, he immediately added, “Wait a minute. That seems too soon. Scratch that thought. Let us make it 95.”

My mother-in-law on the other hand queried, “I’m wondering if anyone has interviewed those very old people to determine if they would have chosen to live to 120 or more, had there been a choice. Also curious to know why you would make that choice [of living to 120], since the possibility of your peers and loved ones not being with you seems to be very real. Or do you anticipate the “community” being a replacement for others?”

According to a detailed survey Pew Research Center conducted last year, comments of my in-laws are well represented in the mainstream of views across the US. As the following figures show, only 38% of people in the US would want to live to 120 and most Americans expect to live to between 85 to 90 years.

Figure 5-1

Figure 5-2

Only about 4% feel that ideal lifespan is between 100 and 120 and another 4% think it is over 120.

Figure 5-3

A majority of people think that living to 120 will be a bad thing for society.

Figure 5-4

A surprising result survey researchers noted is that most of these measures are fairly constant across various religions, gender, education or political party affiliations in America.

In my conversations, I have found that three reasons come up most often when people mull over if they personally want to live to 120:

  1. What would be the condition of their personal health? Will it be joyful living or a painful living?
  2. Will they have financial means to sustain themselves? Being broke is not much fun.
  3. Will their peers and loved ones be around? If not, will it be worth living?

As for myself personally, I feel that there are two major objectives of life: Growth and Contribution.

Thus my rationale for wanting to live to 120 is to simply maximize the time I have available to grow and contribute. Additionally, purposely living to 120, learning some things along the way, sharing with others as I learn, seem to fit in with my personal growth and contribution model of life.

In this sort of context, I see the three common objections cited above, as challenges to overcome as I pursue the goal of purposely living to 120. Moreover, not only I want to live to 120, but I wish to do it healthfully, purposefully and joyfully.

Looking at it another way, I feel, if it is okay to expect to get to 90 healthfully, purposefully and joyfully, why not to 120?

And, of course, as my mother-in-laws suspected, a key purpose for me to write this blog and engage in conversations with family, friends, loved ones is to motivate them and along the way find others who would want to share this journey together.

How do you feel about living to 120?

What do you think it would take to live to 120 healthfully, purposefully, and joyfully?

Please leave comments to this post. I and others following this blog would love to hear your perspective!

Post #4 – Is it even possible to live to 120? – Part II

In the last post on this topic, I concluded that

“As an optimist, when I look at this data, it looks very encouraging to me. First, it is definitely viable to live to 120. It has already been done! Like the four-minute mile, someone has already shown the way.

Second, an increasing number of people are approaching that age with an increasing rate. So, at this rate, I expect by the time my time arrives, dying at 120 will be as routine as dying at 100 today! It might not be very common, but it might not be that rare.”

While I make this informal and what seems like a rather obvious deduction from the data, some folks disagree.

James F. Fries and Lawrence M. Crapo in their book on Vitality and Aging make a compelling argument: while life expectancy has been increasing over the last many decades life-span has been fixed (for all practical purposes – increasing only by 0.1 year per century).

So, intuitively, the chart below may be how one would be tempted to guess the shape of life expectancy curves.

Figure 1
However, they argue, that it is the chart below that corresponds to the reality.

Figure 2

Thus according to their conclusion, while on an average humans are living longer and longer, we are still stuck at dying by the age of 100.

Presenting the data from another perspective in the chart below, as we graph number of deaths against age of death, we observe a normal or Gaussian distribution around certain age at which number of deaths peak. As the life expectancy keeps increasing the curve would look like the IDEAL curve below.

Figure 3

And, as that happens, graph of percent survial rate against age will become “rectanguar” as shown below.

Figure 4

This implies that as we conquer chronic diseases, we will live a healthy long life after which we will succumb very quickly to the forces of nature, within the bounds of a very few years. And, that will define an ideal “natural” death. As we hit certain time limit, all of the cells in the body may burst together like soap bubbles.

Fries and Crapo wrote their book in 1981. So I thought, with all the new research in the last 30+ years, maybe they have changed their mind.

In a more recent review article in the Journal of Aging Research, Compression of Morbidity 1980–2011: A Focused Review of Paradigms and Progress, James F. Fries, Bonnie Bruce, and Eliza Chakravarty reassert the same conclusion and buttress it with more recent studies.

I really like most everything else they assert, derive or conclude in that book- which I would like to talk about in a different post. However, I am personally not sold on this idea of fixed life-span.

It makes me quite uncomfortable. Yeah, you guessed it. After all, my goal is to purposely live to 120!

What do you think?

Have you seen any data, studies or analysis that contradicts this theory about fixed life-span?

Post #1 – Questions I have been pondering lately..

May be it is because I am turning 60 this year or may be it is something else… These are the questions I have been pondering lately:
• What is the object of this game of life?
• How do people die?
• How do people lose vitality?
• What would it take to have a life-span and a health-span of 120?
• How do I want to live the next 60 years of my life?
• How do I contribute at a level that is worthy of my life?
• How do I make a major contribution to preventative healthcare – the area that gets my juices flowing?

In finding answers to these questions, I have been reading whatever I can lay my hands on and talking to whoever would talk to me on this topic.

One of my recent thoughts has been to may be to find other kindred spirits – people who are searching for answers to these or similar questions – and may have even already found some answers!

Also, I am going to use this blog to reflect upon what I come across. Through these reflections I would like to share what I have learned and learn from others.

So, I would love to hear your comments:

Are you in pursuit of a goal to live to 120?

Do you wonder what it might take to purposely live a life of vigor to the age of 120?
