Yes, we all know about that. You're getting too hung up on me saying "lifespans increase." Forget that I said that. Imagine I instead said, "we are optimizing for health in old age more than the ancients did."
> the relative importance of avoiding cumulative damage like radiation has not increased either
It wasn't important at all back then because they didn't know about it.
Do you want to die in agony in your 70s from metastasized skin cancer, or peacefully in your sleep at 80?
My point is that propagation of the species, old age, and rampant melanoma can all exist simultaneously - so what people did in the past re: sun exposure isn't necessarily good advice for us today.
