You’ll have days where you feel fine though and be having fun and enjoying life. It’s easy to say but the initial symptoms might be very mild.
Guessing that ship has probably sailed.
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.
