I had an uncle hit by lightning while closing a gate at his farm. Knocked him about 10-20 feet, burned him down one arm real bad, knocked his shoes off and burned all his toenails off. He doesn't know exactly how long he was unconscious, but it was more than a couple of minutes. After that if it started to cloud up a little he headed for the house. That is the only thing I ever knew him to be afraid of after that.
