oh..
looking at your picture it's obvious that you
(a) had been working in the sweaty confines of a garage all day, tossing around grease ridden tools and having oil drip on you from the car under which you were working.. then decided to go to the gym after work..
or
(b) don't have great personal hygiene and hadn't showered for 3 or more days before going to the gym and just adding to that cess pool of bacteria, dead skin, grime, and oil covering your skin..
guess i was wrong in giving you the benefit of the doubt.. sorry.
