Stress. We all feel it from time to time at work and at home, but to a person who is in poor health, it can be deadly.

Take the job of a coach for a sports team. If you've ever watched a game from beginning to end, sometime during the match the coach will go ballistic, shouting at the officials or players. One coach actually died from a stress related event.

Watch as ABC news follows a coach who is hooked up to a device that monitors vitals during a game. You'll see that it's no wonder a heart attack is a possibility.
