Humans are the sweatiest primates on Earth. They have up to 5 million sweat glands,which produce about 12 litres of sweat per day. It's this propensity to sweat that accounts for our hairlessness and has allowed us to thrive. It might help to remember this next time you're surrounded by sweaty hairless torsos in the gym!
