Hi! I’m a longevity scientist, writer and campaigner. #introduction
My book, Ageless, is out in paperback! ‘A tour de force of anti-ageing science’ – The Times ageless.link
Or, check out my YouTube channel! This is a video on the most promising longevity drugs: youtu.be/RODwPAdtrw8

Checking something in my book and came across this note…I’m proud of past-me for including this pedantry!
The statistic it’s referring to is ‘A 20-year-old today has better odds of having a living grandmother than a 20-year-old in the 1800s did of having a living mother.’

Check out our first news article from @thelongevityinitiative.org: a round-up of longevity science in 2025!
There will be more posts this week on longevity in business, research funding, medicine and comms and policy (Netflix docs and Putin hot-mics, anyone?) so please follow to be first to hear!

To kick off 2026, we’re publishing a week of articles looking back at 2025 in longevity.
The first is 2025 in longevity science—two new drug cocktails make mice live longer, plus clocks to measure the age of your organs and ‘extracellular vesicles’ improve signs of ageing in monkeys.

The future of health depends on longevity science.
Progress in science depends on better policy, regulation and funding—that’s why I founded @thelongevityinitiative.org with @kshoylev.bsky.social.
Help us build the infrastructure for improved longevity policy and education in 2026.

The majority of poor health and deaths globally are caused by diseases that become common with age.
But public policy has yet to catch up with ageing science, and longevity research is underappreciated, and underfunded.
We exist to change that.

Annette, the last of the Dionne quintuplets (the world’s first to survive beyond infancy), died aged 91. RIP.
Fascinating case study of the genetic contribution to longevity: the identical sisters died aged 20, 35, 67, 91 and 91—clearly it’s more than just genes!

On this day in 1989, The Simpsons officially premiered as its own series so here’s a short thread of language facts relating to the show, starting with this…
In the Spanish version of The Simpsons, Bart’s “eat my shorts” catchphrase is changed to multiplícate por cero (“multiply yourself by zero”).

This could well be true in the future.
It’s absolutely not true now. AI is only as good as the data you train it on. We don’t have annual MRIs going back decades for…almost anyone?
I’d far rather a radiologist read my MRI than a pilot, even though pilots are highly trained…

It makes clear that evolution *did* optimise for lifespan (why wouldn’t it?), and that implies intervening in aging might not be that hard…

Having grey hair might mean you dodged melanoma! Serious damage to DNA can cause pigment cells to become senescent, ultimately dying and not dyeing your hair, while cancer-causing chemicals can override this process and allow damaged cells to live on:
Gray hair may have evolved as a protection against cancer, study hints
Aging comes with graying hair, which may be a sign of the body lowering its risk of cancer, a study suggests.
