> Here's an observation: people who've survived longer than most are quick to smile. I like checking out stories about them, because I know I'll see an energizing photo of an upbeat person.

There is the other side.

"Russian Woman, Who Claims to Be World's Oldest at 129, Says She's Had One Happy Day in her Life"

Also, there was a documentary a while back on nursing homes. Pretty much all "people who've survived longer" were miserable. I remember an old woman who out-lived her husband, daughter, friends, etc. I still remember what she said: "Everynight I go to sleep hoping god would take me, but I always wake up." A modern day Sibyl of Cumae.

I don't think "quick to smile" has anything to do with longevity. Misers and misanthropes also can outlive many.
