Why We Age - And How We Can Stop It

The video explores the concept of aging, focusing on senescence, cellular aging, and genetic factors. It discusses how some animals exhibit negligible senescence, allowing them to live longer. The Hayflick limit is introduced, explaining how cells have a programmed number of divisions. Genetic research on aging, particularly in nematodes and mice, is highlighted, showing potential for extending lifespan. The role of caloric intake in aging is also examined, suggesting that lower intake may lead to longer life. Overall, the video emphasizes the complexity of aging and ongoing scientific research.
