This stuff was dangerous, I think everyone going in knew it, as no one else had done this stuff before.

* Climbed Everest * Flew a plane * Make a trip to the Titanic * Freediving * Swam the English Channel * Floated across the Atlantic with no idea where we were headed * Jumped from space without a parachute
