I mean in general it makes sense. As you age your body becomes more brittle, injuries take longer to heal, some you might not recover from at all.

Also psychologically you will have experienced more injuries so you will instinctively avoid doing the same again.

My point was rather that if you know you will die a slow painful death, but not now,and you don't want to commit suicide, you could try riskier stuff that you always wanted to try but would be too dangerous.
