Don't Watch If You Have a History of Heart Disease

wingsuit base jumping from Ali on Vimeo.

I have said that I would only sky dive if I was jumping in tandem with someone I was willing to die with (cause I'm not going out alone). Watching the video of these base jumpers got my heart racing...I have to say I envy the experience, though would never want to take such an extreme leap of faith. Beautiful! Amazing! Certifiable!
