Uli Emanuele is a wingsuit-wearing daredevil who is clearly a bit of an adrenaline junkie, and his most recent jump proves it. 

For the past three years, he has been training for what could be a world record BASE jump where he manages to manoeuvre his way through a tiny two-metre wide cave. One small shift in the wrong direction and he would end up pretty seriously injured, so the resulting footage of his jump captured on a GoPro is an intense but worthwhile watch.
