If there was a gold medal for the bravest people at the Winter Olympics the competitors in the luge and skeleton would surely win.
They use the same courses as the bobsleigh event, but rather than encase themselves inside a mini-vehicle they prefer to lie on a tea-tray.
Obviously, it's not really a tea-tray, but even so, a fairly flimsy-looking piece of plastic isn't much defence against the ice at 85mph.
The main difference between the two disciplines seems to be the direction the athletes shoot down the track in - with lugers going feet first on their back and skeleton sliders going headfirst on their front.
And the tea-trays - really called pods - have no brakes.
