What you're watching is human evolution in action.
If adolescing males didn't engage in risk taking behaviours, we would all be cowering in caves, or worse, we would still be living trees. An ancestral 'jackass' ventured out of a tree, on to the ground, to exploit new food sources. Some of your ancestral 'jackasses' ventured out of the forest on to the savannah. Exposing themselves to untold risk.
Ancestral jackasses on African plains ventured out in the midday sun, when predators and prey were seeking shade. They discovered our unique ability (perspiration) to run down prey.
Vasco de Gama, Ferdinand Magellan, the Wright Brothers, Tenzing Norgay and Edmund Hillary, Ken Warby, NASA's astronauts on the Apollo Program, all of them 'A grade jackasses'.
Enjoy the video. The behaviours you're witnessing are written in your DNA and possibly unique to humans or at least those who aren't accountants or actuaries.
