At 86, James Randi is still amazing:
He has been a professional magician — The Amazing Randi — for more than seven decades, and the skeptical scourge of practitioners of the paranormal for more than four.
He escaped from a straitjacket dangling over Niagara Falls and survived. He chopped off goth-rocker Alice Cooper’s head, and Cooper survived. He sent millionaire faith-healers into bankruptcy, ruined Israeli mentalist Uri Geller’s act in front of a national television audience on The Tonight Show, and wrecked a government research project on psychic powers.
