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.
Problem is that it's not all-or-nothing. Lots of activities have failure modes that leave you severly disabled for the rest of your existence, even unable to do any of the standard suicide activities or even speak/write.
That's all worse than having another decade of a good life.
Or perhaps even a broken hip that never heals is not too great. Now you won't just get dementia, but you'll do so while you can't even go to the toilet yourself even on your clear days.
