If you're going to die of a heart attack, make sure to be in top physical shape beforehand. That's the moral of this amazing story about a triathlete from New York who died during a race. After lifeguards rescued Chris LaPak from the Hudson River, doctors managed to revive him—even though his heart had stopped beating for more than ten minutes. They then brought LePak's brain down to a low temperature in an attempt to halt damage, and waited to see if he would regain consciousness. He did, and is now back to running more than ten miles per week. Do you know any miracle survivors? Tell us their stories in the comments.
