Life is not always fair. Genetics most certianly seems to be an overriding cause in the death of many of the people I know. My father is one of the most unhealthy people I know. Since he was 45 I doubt he excercised more than the distance of his car to the dinner table. At 82 he still weighs close to 400 lbs. Yet almost all of his freinds his age are dead. Three of my uncles and one aunt ( not related to my dad) were never more than 10 lbs over weight. All dead in their early 70's from cancer. My dad's brother was half his size, but died in his early 70's from heart failure. Three people I know were in their early 50's when they had heart attacks. One was riding his bike, one was playing basket ball with a bunch of 20 to 30 year olds, and the other was taking his daily walk. All three were more fit physically than most 30 year olds I know.
