Well, I imagine our cavemen ancestors managed to survive going shoeless in cold climates, but they usually didn't live as long as this guy has. He'll have crippling rheumatism in a few more years, and boy, won't he wish he'd been grown up enough at age 30 to put childish bets like this into the dustbin of his memory, rather than trying to milk a few more years out of his youth...
There I go, being a grump. Oh well, it's snowing and crappy this morning, and this guy just sounds a little nuts.
