A few years ago a co-worker of mine (I'll call him Ed) would come to work almost every day with hamburgers, large fries and a large soda.  Ed was overweight and would sweat profusely all the time.  He always looked tired and worn out.  Ed worked second shift so when he got to work, he'd eat before the shift started.  If Ed wasn't eating hamburgers and fries, it was some other sort of junk food.  Ed didn't eat a normal portion; it was always a large portion.

One day I told Ed, "If you keep eating like that you are asking for trouble!”  Ed made the statement, "You have to go sooner or later so I'm not worried about it!”
