Are they killing themselves because they are severely obese, shooting heroin and drinking 1/2 gallons of Jack every day or are they just not like you? I ask because I know you are an extremely fit person and it may not be a fair comparison. I have to work pretty hard to keep from imposing my lifestyle on family members and friends, but life is more enjoyable with the people you love if you aren't a constant critic (my perspective, my flaw--one of many!)
