“Volcano Boarding”, Djarum

Head up to 17,000 feet. Bring some big oxygen tanks. Have customized snowboards and body suits with embedded lights to turn on at night. 

You might survive the treacherous run down if you are a world-class snowboarder. The start must be painfully slow because the razor-like volcano rock will peel your skin down to the bone if you fall. Finally, you reach the bottom of the volcano just in time to suck oxygen for 15 minutes from the tank, before you pass out.
