Live the rest of it in what ever way feels right (as long as it is legal, more or less).

Going by my parents and grand parents I have around 12 years left. Love to spend them with my grandchildren and help anyone that I can. It does not bother me really. Could be because I have delt with it before. Was almost pronounced once years ago and came back on my own (no pulse & no BP). No big deal now. Not much scares me as I know whats coming. Just like falling asleep (at least in my case).

BTW, I still get up at 4:15, work 6-2:30. I am only 60 but you get the point.
