If you don't have any accidents, don't get any infections, and eat perfectly, your body will still start to fail on its own from the age of 30. But why did evolution program us to age? What is the exact time limit that our DNA can withstand?
In this video, we investigate molecular biology and evolutionary history to discover the true human expiration date.
🌍 What you will learn in this video:
Telomeres and the Hayflick Limit: How the loss of pieces from the ends of chromosomes limits the division of our cells and dictates our maximum life expectancy.
The Disposable Soma Theory: How natural selection prioritizes energy for reproduction in youth, leaving body maintenance as a secondary concern after age 30.
The Power of Autophagy: How prehistoric fasting and scarcity cleaned up cellular waste in our ancestors, and how modern abundance blocks this biological cleaning system.
The Immortal Jellyfish and the Blue Zones: What science has learned from Turritopsis dohrnii and the centenarians of Okinawa and Ikaria about reversing aging.
SOURCES:
1. Molecular Biology of Aging:
Leonard Hayflick (Hayflick Limit, 1961): The discovery that healthy human cells can only divide between 40 and 60 times before dying.
Elizabeth Blackburn (Nobel Prize, 2009): Studies on telomerase and telomere shortening as a cellular clock.
2. Evolutionary Theories of Senescence:
Thomas Kirkwood – "Disposable Soma Theory" (1977): Theory that the body is a disposable vehicle for genes, and that maintaining the body after reproduction is not energetically viable for evolution.
Yoshinori Ohsumi (Nobel Prize, 2016): Discovery of the mechanisms of cellular autophagy activated by caloric restriction.
3. Clinical Studies and Regenerative Medicine:
The TRIIM Trial (2019): The first successful clinical trial demonstrating the reversal of human biological aging through thymus gland regeneration.
