Patent granted! “Cellular reprogramming to reverse aging and promote organ and tissue regeneration.“ Super proud of the team’s invention of the first truly safe age-reversal technology - for healing injuries, treating diseases, and hopefully extending human lifespan @y_ryan_lu

The most dangerous myth in medicine is that aging is natural and therefore acceptable

Stem cells don't run out, they get told to stop dividing and that instruction can be renegotiated

Metformin's anti-aging reputation rests mostly on people who already had diabetes

Evolution never optimized you for a hundred healthy years, that's a job you must finish yourself

The best longevity drug available today is exercise and building muscle 💪

Your future health isn’t determined by your birthday. It’s determined by what you repeatedly do between now and then 💪

The body responds to intensity more than duration. Even ~4.4 minutes of vigorous daily movement associates with ~26–30% lower mortality risk join.lifespan.com/577uh3zr

Aging is noise in the system and noise can be reduced

The question is not whether we age but how fast

Cells respond to mild adversity by becoming stronger

The more stable the system the slower the aging

Aging is a drift away from optimal gene expression

Longevity comes from maintaining order in complex systems

Cells do not forget how to be young, they lose access

The genome largely stays intact. What changes is how it is read

Biological clocks are entering the medical mainstream

The body is always responding to adversity and abundance

Cells are resilient until pushed past repair capacity

If aging is corrupted software, it can be reprogrammed

Every system in the body is adapting all the time. You are in control

Biology is not just chemistry, it is code

The body remembers youth even when it looks old

Aging is loss of information and the surprising finding is information can be restored

From 2008-2024 I was accused of hyping (a common slur) for suggesting that changes to the epigenome might cause aging and that therapeutics could "allow us to reset the epigenome to a more youthful state." - Oberdoerffer & Sinclair (2009) Success has many fathers, while failure is an orphan

Most people wait for disease.
By then, biology has already shifted

Type 2 diabetes is associated with substantially higher mortality risk www.nejm.org/doi/full/10....

Higher omega-3 levels are linked to ~15–20% lower mortality risk. More here: www.nature.com/articles/s41...

Biology doesn’t care what’s “normal.”
It responds to signals. And it can be changed

Muscle mass is a stronger predictor of survival than BMI in older adults Read here: www.sciencedirect.com/science/arti...

Prevention is delayed treatment of aging

The goal isn’t longer life.
It’s longer function and performance. Longer life is the side effect

The earlier you intervene, the bigger the payoff

About 7,000 steps/day is associated with ~50–70% lower mortality vs low activity jamanetwork.com/journals/jam...

Fixed it

The future of medicine is treating causes, not symptoms. Aging is the main cause of disease

Longevity isn’t about perfection.
It’s about direction

You don’t need more time.
You need better biology

Aging is the biggest unmet medical need by orders of magnitude

REMOTE CONTROL MICE! A group from Seoul has just published in Cell that they’ve discovered a crazy-weird protein (Cyb5b) that can be used to turn on any gene when exposed to EMFs. They used it to turn on OSK and extend the lifespan of a progeroid mouse. Amazing! www.cell.com/cell/abstrac...
