Ramakrishnan points out, "It's a peculiar situation because we're a collection of cells and when we're alive, millions of our cells are dying. ... When we die, most of our cells are still alive. And so what does it mean to say you die?" This highlights the complexity of the dying process beyond the mere cessation of life.
Ramakrishnan emphasizes the paradox of life expectancy versus lifespan, stating, "Humans have seen a significant increase in life expectancy over the past 200 years but not in overall lifespan. Nobody on record has lived past 122 years." This raises questions about the nature of aging.
