Sucks...not even all the money in the world matters when you lose your health.
Honestly, I always hoped for a quick and painless death but if possible, while I'm also both mentally and physically healthy (relatively).
It seems after a certain age, most lose one of the other, and neither condition is fun.
Worst part, to me, is becoming a burden for your loved ones. I don't mind taking care of others as I have been but I wouldn't want to put that burden on someone else.
