In this case, this surfer is hanging down the face of ten stories of water.

Garrett McNamara broke the world record by surfing a 100 foot wave in Portugal on January 28, 2013.

Garrett to himself: THIS IS SO COOL!! BUT I'M GOING TO DIE! BUT THIS IS SO COOL! BUT I'M GOING TO DIE! BUT I ALMOST DON'T CARE! THIS IS SO COOL!

AND he survived it! :-)
