This Guy swims to work.
I'm all cool with that, but it seems like he's going downstream and he uses his inflatable waterproof pack to float a little..... why not just sit on an inflatable tube or use something motorized? He says he's doing it for speed.... and doesn't mention swimming home upstream.
It's possible he might just be a nutso attention-ho, but it could be a new thing....
Perhaps those without convenient rivers could use the sewers mutant ninja turtle style?
