Smiling at Karen and Ron here-
My boyfriend (oops- fiancee now) always says he wants to die around 50 or 60...
Proximity to mortality (especially in those you love) can shape your outlook a lot. My grandfather's words, before open-heart surgery: "I'm scared... I don't want to die." And I harbor no illusions- his last words, before he suffered a massive heart attack and coded in dialysis- "It's starting to hurt." Was he scared? I'm sure... Looking into enough strangers' eyes when they just know something's about to go wrong... when you walk in the room and they are grey and sweaty and say "Nurse, I feel like I'm going to die..." Those are words a nurse hates to hear, because it usually means that they will- it's a sign of major problems.
Nobody looks happy when they say those words. I don't care if they are ninety years old with a colostomy and being fed through a tube in their stomach and have fifty drains sucking secretions out of them- if they are still with it enough to say those words, they are scared.
Maybe it's just my nature... but even before I worked in healthcare- I knew the look... my grandparents, my mother (not my dad- post open-heart, and still with dire health problems, he kept pushing the PCA button and cursing about how "there's not enough morphine in this whole hospital to get me high!" lol) but I don't know... it seems like hubris to me, and has for years, to make a declaration like "I want to die when I'm 50 or 60." As if you know what your life will be like then. As if you know you will have nothing more to live for. As if you know, after that point, your life will no longer be worth living- which, to me, seems like an insult to anyone over the age of sixty, especially if they still have a desire to live. And, most irritating to me, as if you are better or more priveleged than any of us other poor saps who are burdened by the infirmities of age... as if you are exempt.
I just think, to me, I like to play things more by ear than to make rash generalizations... and if my time comes, before or after 60, I can only hope I will have the luck to know in advance and the grace to get my affairs straightened up and get into hospice where I'll be made comfortable.
So, I guess, long story short, I don't really love or hate the idea of living to 100- I just like the idea, as Ron puts it, of living until I lose hope.
