If there's one extreme sport which makes us sweat just thinking about it, it's got to be nutters' favourite, base jumping. Be it from building, antennae, span or good old earth, taking the plunge with nothing but a parachute attached to ones back seems at best, foolhardy.
Also high on our list of things not to try drunk is motocross. Keeping a motorbike upright on tarmac is tough enough without introducing nature's own choice of terrain. It's a broken ankle, wrist, leg, arm, back, finger, neck, hip, pelvis waiting to happen.
So why not combine the two? Well, it gets them both out of the way on the same day at least. And it does look good on film. Click below to watch Julio Munoz ride off a Chilean mountain.
