David Blaine to stay awake for a very long time. . .

“It’s been tried before. In 1959, Peter Tripp stayed awake eight days, but it resulted in permanent brain damage. In 1964, 17-year-old Randy Gardner did it for a high school science project. He lasted 11 and a half days but recovered fully. No damage. A guy in London tried but fell short.”

Good luck with that.
