Yesterday I visited my grandfather. He's 89 and not doing so well. The battery in his pacemaker is dying and they need to recharge it, only that would require surgery which he's not strong enough to take. So my grandma and dad are facing the decision of what to do. I have to admit, I was thinking gosh, his quality of life right now is so low... why put him through surgery with the risk of infection and all sorts of other problems. But then when we visited him, I saw a spark of himself and he made me laugh several times and I didn't want him to die. But then I thought I'm just being selfish--wanting him to stay alive for my own sake.
So I dunno... all of that to say that sometimes I think life drags on too long and I hope that I die in my 60s or 70s in a motorcycle accident or a heart-attack on my bathroom floor.
Overall though, I think I agree with B&D and I like everything he said on the subject.
