What else would you have them do?

One of the joys of maturing is reaching the point where you TRULY do not care what anyone else thinks. When I was so much older than I am now, I said I didn't care but I really did. Now that I am younger, I don't even bother to say that I don't care, but I really don't.

I personally would prefer to die with my boots on. If I were an aging rock star I would hope to die while cavorting like an idiot on stage.

There's a lot of rhetoric in this thread that is based upon very bad assumptions about what is proper behavior for people of a certain age.
