I'm 6'2" and weigh 174#... and if it is above 70° I start to sweat. Im only 3rd generation American and my ancestors are all from Norway and Sweden (hooray for not race mixing) and I firmly believe that this is due to "muh genetics." Lolz... Mark your calendars everyone, a human sized person blamed their genetics!! But really, I'm far from being fat and I am an active person, I just sweat when it gets warm.
