Programmed longevity, youthspan, and juventology – lifespans and Healthspan

Volter Longo has some interesting new ideas regarding how we look at life expectancy, lifespan. He recommends thinking about spans in terms of youthspan (peak health 20-60) and Healthspan (oriented to disease free stage and the older phase (65-120).

also check David Sinclair’s new book Lifespan: Why We Age―and Why We Don’t Have To — is a really great book! Highly recommended …. packed with information … some should be taken with a grain of salt or maybe with a Sirtuin activator like NMN 🙂

I am doing this because nutrition, diet, and exercise are
thing we can actually control.  If we educate ourselves and.  the next generation, we have a much better chance at a higher quality of life for a longer duration, and also less expensive government.  The way things are, health care costs are  
skyrocketing.  If we get healthier, costs will go down, taxes will fall, and we'll all be happier all around!

Parabiosis, Reprogramming, and Diet

Live longer … think “Epigenetic Diet”.

Pay attention to “The Aging Epigenome” – paper by Lauren  Booth  and Anne Brunet (over at the  Glenn Laboratories for the Biology of Aging, Stanford U).

also pay attention to Brian J. Morris, Bradley J. Willcox, Timothy A. Donlon , Genetic and epigenetic regulation of human aging and longevity. Bbadis (2018), doi:10.1016/ j.bbadis.2018.08.039

Get familiar with Sirtuins,   resveratrol,   spermidine,  metformin, selenium,  learn to enjoy  green tea, broccoli sprouts and soybean products.

OK … exercise definitely helps!






Nutrition, Diet, Health, Medicine

Continuing on the reference. building … interesting insights emerging.  Lots of fad diets, some kernels of truth, lots of confusion, lots of marketing. lots to sort out. Somewhere along the development,  the connection between inputs and outcomes will become much clearer. Especially if one really isn’t in the huckstering business.

Want to avoid lung cancer?

Listen. … Just don’t smoke to start with … No one can guarantee what happens … but, if you smoke you triple your risk over people who never smoked …

Framingham Heart Study researchers find that former smokers who quit smoking 25 or more years ago still have three times as much risk of developing lung cancer compared to people who have never smoked.

The Mediterranean Diet and Nutritional Adequacy: A Review.

Castro-Quezada, I., Román-Viñas, B., & Serra-Majem, L. (2014). The Mediterranean Diet and Nutritional Adequacy: A Review. Nutrients.

Interesting … the claims

The Mediterranean dietary pattern, through a healthy profile of fat intake, low proportion of carbohydrate, low glycemic index, high content of dietary fiber, antioxidant compounds, and anti-inflammatory effects, reduces the risk of certain pathologies, such as cancer or Cardiovascular Disease (CVD).

The inclusion of foods typical of the Mediterranean diet and greater adherence to this healthy pattern was related to a better nutrient profile, both in children and adults, with a lower prevalence of individuals showing inadequate intakes of micronutrients.

We’ll be reviewing this and related studies in the overall evaluation …

later …


Mediterranean diet and telomere length

Looking at


Conclusion In this large study, greater adherence to the Mediterranean diet was associated with longer telomeres. These results further support the benefits of adherence to the Mediterranean diet for promoting health and longevity.”

So,  that seems promising … the question….. can you ‘stick with the diet’?  Of course, there are other studies that provide other results.  How does one resolve the discrepancies?

Stat tuned … Ideas coming soon 🙂

this should make one humble. …

We are only just beginning to understand the full majesty of life on Earth. Although 10–15 million eukaryotic species and perhaps trillions of bacterial and archaeal species adorn the Tree of Life, ∼2.3 mil- lion are actually known, and of those, fewer than 15,000, mostly microbes, have completed or partially sequenced genomes


Pretty Ambitious!  … and rather important!

Bats are the longest-lived mammals for their size

I didn’t know that 🙂 apparently others do … cool!

Only 19 species of mammal are longer-lived than humans given their body size, and 18 of these species are bats

Watson for Oncology (WFO) – more details

Back to Watson for Oncology (WFO). … so today was deep dive day to look at what papers were written specifically re WFO.

So,  on Sunday, June 23, 2019, using Google Scholar … the list below is of  the main useful things I could find.


  • Shows promise
  • Not ready for solo flight (i.e. needs clinicians to work with it).
  • Benefits from adding diagnostic tests liken GEA (Gene expression assays)
  • Keep working on improving WFO, and understand specifics better.


Literature I looked at, will look at it again in more detail, and provide further insights.
