I don't think suicide is ever passive - more a deliberate act.

Foolishness, that's another story. Adrenaline junkies aren't suicidal. My SIL is morbidly obese, is non-compliant with medical advice, but is the first one to call an ambulance when she has chest pains. She doesn't want to die but her lifestyle choices suggest otherwise.

I don't think refusing heroic measures to stay alive is suicidal - isn't quality of life a better choice than quantity when there are no guarantees?

Most smokers I know are sure they are the ones who won't have any ill-effects, even as they hack constantly. Denial is a strong persuader.

Anyway, that's my take, I'm sure you'll get a lot more points of view!
