ok i realize this is insane but, i sincerely think that everyone who is able to should skateboard, or do something else with a similar risk of singular, non repetitive stress based injury.
when i am on the floor, laughing, clutching my shin because i've used the magic of simple machines to slam a block of wood into it at mach 3? that's Life baybee. i am Alive.
in my experience, way more than exercise, it's good for my brain to take these sorts of controlled risks. and for those risks not to pay off sometimes!
