TED-Ed: Why do our bodies age? - Monica Menesini

The video explores the concept of aging, starting with the story of the oldest known person. It discusses the biological limits of human life, the challenges in defining aging scientifically, and the intrinsic and environmental factors that contribute to aging. Key physiological traits, such as genetic damage, mitochondrial decline, and epigenetic changes, are highlighted. The video also covers the decline in cellular regeneration, telomere shortening, and stem cell function. It concludes by speculating on future technologies that might extend human life and questions whether we desire such longevity.

What role do mitochondria play in the aging process?

What changes occur in stem cells as we age?

What are some potential future technologies that could extend human lifespan?
