Not sure. I've always been shy in real life (not on the net), and have dressed in the same style for years (black plain tshirt, levy jeans, asiics sneakers). I'm not one to come off as confident or even stylish. Heck, I prefer to use the same style shirt because I cant match colors for the life of me. But Im pretty athletic, and run about 20-25 miles per week. So it might be that.
