Anyone ever tell you to take a cold shower? I’m not sure if anyone ever told Lewis Gordon Pugh to cool off that way, but it seems he’s done one better than that. Well I wouldn’t say better, but a lot colder. Last week, Gadling.com reported that Pugh successfully swam a kilometre of arguably the coldest waters on Earth – Pumori Lake in the Himalayas, near Mount Everest. At 17,700 above sea level, Pugh’s little dip set a world record for the highest altitude swim ever recorded, and the longest known time anyone’s swam, let alone survived, a glacial lake swim, at 22 minutes and 51 seconds. brrrrrrrrrr.
