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

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...
Are annoying age spots due to epigenetic drift, a likely cause of aging?
"Consistent with the Information Theory of Aging, we found a global disruption of tight epigenetic regulation"...at genes involved in DNA repair, inflammation & mitochondria
Fascinating!

Cardiorespiratory fitness is a strong and consistent predictor of mortality across populations jamanetwork.com/journals/jam...
We don’t lack tools. We lack urgency
Longevity science is accelerating faster than expected
We are closer to controlling aging than most people realize
Small interventions shift long-term trajectories
If we can slow aging, we delay multiple diseases at once
Large meta-analysis of ultra-processed food intake is linked to multiple chronic diseases, not just obesity www.bmj.com/content/384/...
Biology is programmable
Semaglutide reduces major cardiovascular events in people with obesity without diabetes (SELECT trial)

Most people wait for disease. By then, biology has already shifted
Deep sleep enhances glymphatic clearance of brain waste, including amyloid 😴 🧠 www.science.org/doi/10.1126/...
The question is no longer if we can intervene in aging. It’s how safely and how many times
~4.4 min/day of vigorous “incidental” activity is linked to ~26–30% lower all-cause mortality www.nature.com/articles/s41...
We don’t die from age. We die from aging. And the letter is malleable
Age is not fixed. It’s dynamic. This is one of the most remarkable discoveries of the century
Most people treat aging as fate. Biology treats it as a process that can be changed
Medicine is shifting from reactive to predictive
