Alexander Polli is braver than you. Or stupider. Or both. Regardless, he’s definitely better at BASE jumping and flying through narrow openings in rocks while flying in a wingsuit at 155 mpg. (And we use the word “flying” loosely, since it’s really more like controlled falling.) Regardless, the video he takes with a helmet-mounted cam is enough to make your testicles rise back up into your body cavity. In other words, it’s awesome.
