dumbest thing I ever did was forget to put my goggles down before going down a ski run. I had tears coming out of my eyes from all the wind, and while I had my hand up to wipe my face, the poke-end of the ski pole hit a tree, forcing the handle-end to smash my skull and knock me out right in the flats at the bottom. The colour on my skin which lasted a good month looked like I had been beaten to a pulp in a back alley. It happened 10 years ago and there's still a nice scar below my right eye. Good thing my stupidity didn't cost an eye though!
