I recently went to a new (to me) neurologist who earlier this year suffered a heart attack. A fit man, well exercised so not an obvious candidate.
I suggested that he might be able to take something positive from his most unpleasant and concerning experience. In his case letting go and taking things a bit easier. Rebalancing his life. He is doing just that, though not because of me. Just common sense.
As for the idea of a body parts warranty, I’ve asked myself quite often, typically when yet another part from my 17 years old car needs to be replaced, why can’t I do the same with my body? I’m 76 and I’m in quite good working order. Still, I’d be glad to replace or at least upgrade certain body parts.
However, if there had been a warranty, it would by now have long expired.
