2% bodyfat huh? congratulations you should expect to die within the next few minutes. and theres more than just muscle and fat in your body, once you stop playin with blocks at school you'll learn about that. regardless, you are lying, just as you did about paying for your skis.
On a side note even if you have more muscle than someone that doesn't make you stronger than them. Strength and muscle size arn't related as much as you think.
