Slovenian Martin Strel is a superman who "swims for peace." (He explains how the Dickensian aspects of his early life taught him to withstand pain.)
He holds several Guinness Book swimming records and plans to conquer the Amazon next month. It's never been done, but Martin plans to swim 3,375 miles of the world's most treacherous river.
Reuters describes what a disgustingly messy endeavor it will be: "Buckets of animal blood will be loaded onto support boats to distract flesh-eating fish and reptiles during the 52-year-old's 70-day odyssey -- which would break his own world length record for a swim. "
If all goes as planned, Martin Strel will be swimming for 70 long days.
