I am the 2011 USA Memory Champion and hold the US record for memorizing a deck of cards in 63 seconds. Here I attempt to memorize a deck of cards at the South Col of Mt. Everest (camp 4), which is situated at 26,000 ft above sea level, in the Death Zone. I am receiving a third of the oxygen I normally would get at sea level. See what happens…. (This was filmed entirely with a GoPro HD camera)

Please share this awesome info!
