Strangely you become more risk averse and stuck in your little loops as you get older and the routines you have become fine, good even.
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.
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.
