Minda Matter.

Just got Nat Geo's fabulous article titled, "American becomes the first to ski down Everest's most challenging route." The story details how Jim Morrison, a legendary Tahoe-based skier (not the other one), summitted Everest (climbing 29,032 ft) for the sole purpose of riding his boards down the mountain's most difficult and elusive line, a linkup of the Noreen and Japanese Couloirs. A couloir, for non-climbers, is a "narrow and steep gulley," and these, in particular, follow the "falling water line," which is how a drop of water would reflect the pull of gravity. 

Super steep. Unrelenting. 2,561 meters — 8,402 feet — in total.

For us mere mortals, the sweetest part of the story: Morrison is fucking 50 years old. Or, as a lot of people in my line of work would call him, "ancient." 

Take that, ageists everywhere. In the battle of mind over matter, you bet we mind, and your sad mischaracterization of human talent and skill don't matter.
