A lecture by my favorite biologist, Michael Levin, about his (cybernetic) theory of aging. The ship of Theseus is not really the physical ship, but the plan of the ship that exists in the minds of the workers. It starts to age and degrade when the workers forget the plan or drop the goal of maintaining the ship. Lifespan (and healthspan) extension could happen by reminding your tissues about their purpose. https://www.youtube.com/watch?v=EeKnxXPy3Xs
