LIFE EXPECTANCY & LIFESPAN: WHAT'S THE DIFFERENCE? And What's Health Span? [2021]

LIFE EXPECTANCY. LIFESPAN. HEALTH SPAN. What do these terms mean, specifically? And how do they relate to concepts like longevity and extending life?

Join me today as we examine each of these terms. And another...morbidity. We'll see how these terms to each other and what factors go into determining how long each is.

Finally, we'll examine some models for extending lifespans and we'll see how extending the health span and compressing morbidity can impact longevity.

Life expectancy has jumped, mainly because infant survival rates are much higher than they once were. Poor hygiene and nutrition, less advanced medicine and more communicable diseases meant that newborns in Ancient Greece and Rome had a much lower chance of surviving their first few years. But by combatting age-linked illnesses, we can extend our life and live until a hundred and fifty. I too have spent a lot of time confused with the push back to ending death and extending human life. As more people see it as a true option, I hope they’ll move past the fear of death and see it’s all really quite possible! It’s through Dr. Sinclair's podcasts I learned about Vitruvin Anti-Aging Supplements and ever since I am taking this NMN supplement, it radically changed my life.

I know that both myom and dad made it past 88, which my dad had passed last away last year. Of natural causes. My mom will be 90 in November. Her mother lived till she was 96. Not saying my mom has not had heat surgery as she was a smoker and heavy drinker. I am 67, still ride a bike daily and just received my AA. I I believe stem cell research will bring to us longevity but with consequences. Thanks for the life spans.

My goal is to get to at least 127. (I'm not joking!) But for that, you have to consume zero sugar, zero alcohol, healthy fats, be active, lean, and fit, (basically be an athlete or, a "lifelete", use some superfoods, fast regularly to rid your body of all useless and damaged cells, not smoke or use drugs, sleep a lot, have a good mindset and ALSO have good genes. I was lucky. My father was still swimming across a river (and back) at 78 and repairing the roof at 92. I'm 45 (can't believe it, my physical age number never feels right LOL) and most people think I'm around 27. 👍

Great episode man I’m Mexican American and am the only one taking health span and longevity seriously. I am also 25 feeling older lol just started my journey a couple months ago

Lol I had an argument with a tour guide at a US frontier fort historical site. She casually dropped into her historical tour that people in the frontier days only lived into their 40s and 50s. I corrected her and said she was mixing up average human lifespan and longevity (or life expectancy) - she was incredulous about it. I said "do you really think humans 150 years ago hit old age and started dying of natural causes in their 40s and 50s?" and she said yes because life was so hard on the frontier that people aged faster. I told her this was physically impossible and explained what AVERAGE human lifespan statistics mean, and talked about childhood and infant mortality, vaccines, antibiotics, etc etc etc.... she just got angry at having her authority challenged. But I told her that there were a lot of old farts around back then, in their 70s, 80s, 90s. Just go read a few tombstones. That shut her up.

having three or more
versus two children is related to worse
late-life cognition. They also found that
this effect is similar for both men and
women.
Fertility may affect late-life cognition
via several pathways. First, having an
additional child often incurs
considerable financial costs,
reduces family income and increases the
likelihood of falling below the poverty
line, thus decreasing the standard of
living for all family members and
possibly causing financial worries and
uncertainties, which could contribute to
cognitive deterioration.

David Sinclair seems optimistic based on his research and hypothesis. But it also seems that cloning oneself to be closer to reality?

I had a question for you and your viewers. I do intermittent fasting to keep my weight in check, but also I have read that it can help with inflammation, immune system, autophagy, as well as other things. I have read where fasting can lower your white blood cell count because it resets the immune system. I wonder if this explains why my white blood cell count appears low. One concern I have had is that if my immune system is being "reset" and indeed this effects my white blood cell count, will it compromise the effects of the COVID vaccine. I was vaccinated in January and I have wondered if fasting, which I have done up to 3 days would effect my immunity.
Thanks

Hi Lance, your comment pls to incredible long lifespan of Patriarchs in Genesis that reaches as long as 500-800 yrs and 470 something on average. Thanks.

How does the hormones a person has affect the aging and cell repair? How can they be manipulated?

Is it possible that calmonts age is due to her high chocolate consumption?

Since I am not on the inside track of any research at any major institution such as Harvard, Yale, or Stanford or the equal world wide, I can only say what I think based on very public information and logic. That disclaimer aside, it appears we (they) will have the major breakthroughs in the next ten to twenty years. However, as those things go, it will take another decade to get the processes re-researched and into the public arena. So, available to you and me in let's say 25 years but there is a caveat.
It won't be available here in the States. My guess / assumption is the breakthroughs will likely come from American or possibly European university labs and be tested and made public in Asia. Probably Japan or China first as they are the most motivated from population aging issues and have fast-tracked longevity procedures through their medical systems (yes, China does have a serious population problem resulting from the one child program and the resulting common practice of aborting female fetuses).
Japan, China, or Timbuktu in Africa, count me in!

In 5-10 years the rejuvenation will be available for rich people. In 25 years, it will be available almost for anybody.

When the science can regenerate an entire limb or reverse a malformed organ from birth by contracting it and then having the body grow the limb in a healthy way. In other words regrowing teeth, completely regenerating burn victims, fixing dwarf limbs or genetic conditions. When the science can do that then true amortality will be achieved. It will be the core which the other therapies will be based on.

As I umderstand it, in Denmark where we have universal healthcare, the period of morbidity is somewhat maintained between individuals who live longer, and people who live shorter. The analysis I heard referred by a lecturer was that there for most people is a hockey stick effect, where peoples increased cost in the health care system lasts on average 7 years.

So one could imagine that there is a tipping point where declining health starts to become visibly more costly, and an average time of death 7 years later. This could indicate that morbidity has a somewhat stable length, or that the danish healthcare takes 7 years to finish us of! 😁

I am afraid I have no link to articles, I picked it up in a lecture about biotech innovation many years ago.

50 years, this will be market ready. Unfortunately, this is the driving force of the reason it will take this long to be market viable.

[tamerabetts]

You're lucky to see 70s barely early 80s.. Life span is not that at how many people that died these past few years.

[davidgifford]

To be honest I find the theory that Madam Calmont was in fact her daughter impersonating her in order to continue to collect her mothers pension insurance money, more plausible than a smoker living to 122years. Regardless, these extremely rare aged individuals beyond about 115years must be considered “outliers” and not helpful when discussing the top end of realistic natural life expectancy. For most of us health conscious non-smokers attaining anything beyond 95 -105, is going to take sone cutting edge life extending interventions.

[donaloriordain]

I do not actually believe the life expectancy dished out. I see Ukraine and Russia having reasonably high life expectancies and in fact both increasing in the last 3 years, can this be true?, consider at least 100, 000 killed in the war (some would argue the real figure to be half a million or more) and these are not aged over 70 years. Consider their hospitals being overrun with wounded, consider injuries leading to death and consider infrastructure particularly in Ukraine being seriously damaged, how could life expectancy be up? Are normal health services available in either country? Are the people at home where the man or woman of the house is away at war better off without them? Are their houses better with a war on ? Are their elderly and vulnerable being cared for even better while there is a war on? Am I missing something?

[christopherellis]

Life expectancy is a meaningless term. For example, of the five people in the Cromagnon grave site, one was a baby, two were about twenty, and the other two were in their fifties. (0+2×20×2×55)=150÷5=30
