Turning 50 is definitely a big deal, and Will Smith definitely wants the occasion to be memorable. Smith decided that he wanted to bungee-jump 550 feet down into the Grand Canyon from a helicopter. I don't know if that's some sort of standard death-defying outing you can just order up, or you have to do some serious wrangling to make happen. Whether it was easy or tough, Smith got on the helicopter, and then got off - the hard way. He says he went "from complete, absolute terror to the most magnificent bliss." Check it out - maybe you can arrange one for your big day!
