North Pole

Last night I met someone who rather knocks the Felixstowe Ferry crossing and even the Humber Bridge crossing for six. His name is Lewis Pugh and he swam a kilometre at the North Pole and has swum the full length of the Thames to raise awareness about global warming. He's the first and I think only person to have done these swims. He was saying that he is able to psychologically raise his body temperature. So that when he gets into icy water he is sweating. I'm hoping that I have picked up his technique for our Christmas swim. It is worth looking him up on wikipedia to see what he has done.
