August Longevity Update


Hello and welcome once again to this month’s longevity update. After an uber-busy summer work wise, I’m back to famine (such is the life of a contract teacher), but at least it means I can devote more time to longevity and get these newsletters sent out more promptly!


I’ve been asked by a few people how my longevity regimen is working out, and truth be told I have absolutely no idea! I have not noticed or felt anything, and the grey hairs on my beard have not magically reversed back to black. But, then again, I wasn’t expecting to as I already lead a fairly healthy lifestyle (daily fasting, healthy diet & plenty of movement), and haven’t yet felt the physical or mental effects of ageing. I have been taking some basic biomarkers (weight, blood pressure & blood glucose), so maybe once I get around to analyzing them some trend will emerge. Basically, I’m trusting in the science and hope that my regimen will provide benefit in the long term.


I had however hoped to pass on some anecdotal results via my parents, who being in their late seventies, could potentially see some noticeable results. Unfortunately, despite having all the necessary supplements & detailed instructions since June, they had not started yet (“once we’re back from holiday; once the patio is done; once etc etc…”). I finally lost it a couple of days ago and had to be quite brutal to them. I told my mom I wouldn’t speak to her again until she started and asked my dad how much he had enjoyed her stroke last year and if he was looking forward to the next one. He was quite understandably shocked, but it did the trick and they started that very same day! I will provide an anecdotal update in a few months time.


In the meantime, I’ve added a few sections to the end of the supplementary information, as there is so much exciting news out there and I didn’t want to clog up the round-up section. The new sections concern cellular reprogramming, young blood factors and miscellaneous, where you can find stuff on stem cells, ageing theories & how optimists live longer!


Follow me on Twitter @ChrisPollyanna1 for the latest updates! (after a two month hiatus… )


Finally – please feel free to forward this email to anyone who might be interested, and please let me know if anyone would like to be included in my mailing list! Also, any feedback is greatly appreciated… J
NOTE: I’ve been having trouble linking to the science journal hacking site www.sci-hub.tw , so am only including Full Text links to articles not behind a paywall. I have still been able to download most of them, so if there are any that you are after, I can send them upon request, or you can simply copy the paper’s URL into the site above to get +95% of papers hidden behind paywalls.


August Round-Up:

In the same vein (pardon the pun) the following announcement is from a company which uses a proprietary fraction of young blood plasma to try to treat age related conditions. The promising top-line results here are for Alzheimer’s (full results to be presented at a conference in December): Alkahest Announces Positive Top-line Data from Phase 2 Study in Mild to Moderate Alzheimer’s Disease

  • Finally, the current issue of MIT Technology Review is devoted to longevity - Old Age Is Over! – if you want it with some very interesting articles (LEAF commentary). Unless you buy a copy or subscribe digitally, you are only allowed to access three articles per month. Here are my three recommendations:

Has this scientist finally found the fountain of youth?, about partial epigenetic reprogramming, the leading story from last month’s update.


The anti-aging drug that’s just around the corner, about the Rapamycin analogue mentioned last month (I can’t let a month go by without mentioning Rapamycin, can I?).


The transhumanists who want to live forever, about the biohackers taking matters into their own hands.

Videos to watch:


An eloquent polemic about ageing and what we should do about it by Reason, the author of the blog Fight Aging!, which I read on a daily basis (& whom I got to meet at the conference in July). The longevity field is roughly divided into two camps, those who think that it is programmed and those who think that it is the result of wear & tear damage. He is firmly in the damage camp. As a counterpoint, underneath is the programmed ageing view as espoused by Josh Mittledorf, another blogger I follow (& met as well), in relation to the cellular reprogramming study talked about last month.

Josh’s indirect response:
Further sources of information:
Fight Aging! (run by the gentleman in the video above, quite opinionated about the damage theory of ageing)
Life Extension Advocacy Foundation (LEAF) (best source of longevity information on the web)
Longecity (good forums where the self-experimenters reside!)
Aging Matters (good blog from the programmed ageing side)
Research Institutes:
SENS Research Foundation (I have a recurring monthly donation)
Buck Institute


Private initiatives:
Age-Reversal Network (good information & forums for those interested in self-experimentation – this is where I found how to get non-prescription Rapamycin)
Better Humans
Gerontology Research Group
Lifespan.io (Tied together with LEAF, I have a recurring monthly donation)




August Supplemental Information


***Disclaimer 1 – As should be self-evident to anyone receiving these emails, I am NOT a doctor or indeed a scientist. All the information pertained within is for information purposes only; use at your own risk. Please consult with a healthcare practitioner if needing medical advice.***


**Disclaimer 2 – In no way should supplements be a replacement for an unhealthy diet or lifestyle. A varied, plant dominant dietary pattern is the cornerstone for health. Try to eat the rainbow – the greater the variety, the greater the benefit. Even though I might take a supplement derived from a plant source, I still eat the plant in question. Also, make sure you move as much as possible – that is what we evolved to do.**


*Also bear in mind that most of the studies mentioned below are in rodents, not humans. Rodents, needless to say, do not always react the same way to drugs as humans do – witness the countless times cancer or another disease has been cured in rodents only to subsequently fail human trials. I have *bolded any human trials.*


Fasting/Dietary Restriction – certainly the cheapest & also one of the most effective anti-ageing interventions currently available. It comes in many flavours, but I fast for at least 12 hours every day.
*Alternate Day Fasting Improves Physiological and Molecular Markers of Aging in Healthy, Non-obese Humans. Full Text
*Recurrent circadian fasting (RCF) improves blood pressure, biomarkers of cardiometabolic risk and regulates inflammation in men. Full Text

Non-prescription Supplements (in alphabetical order)


Astaxanthin – which is behind the pink colour of salmon & shrimp. Considered the most powerful carotinoid, it has anti-oxidative, anti-inflamatory, anti-cancer, neuro-protective and skin-protective qualities. I take 4mg daily.

Great stuff Chris! Thanks for the valuable review.

Thanks Chris. Please keep the blog going!

Nice job, very informative.


Just a question I am wondering:



Another potential mechanism for improving longevity is to increase our telomeres (protective caps at the end of our chromosomes) via activating the enzyme telomerase. This paper looks at various nutrients which do so – main take away: olive oil is very good for you! Discovery of potent telomerase activators: Unfolding new therapeutic and anti-aging perspectives. Full Text



Gotu kola is said to be rather toxic for the liver, but oleanolic acid seems to be good for the liver, so could the negative effect of one be compensated by the other? Imagine taking one compound that increases telomerase 8 fold and another one 5 fold at the same time. Now that would be strong stuff..
