What have you been doing for the past hour? Reading? Working? Working out? Think again: youve actually just shed 600,000 particles of skin in the last 60 minutes. That is very impressive. And disgusting. By the time youre 70 years old, you will have shed 105 pounds of skin in your life time. Dont be too upset though: every square inch of your skin has 32 million bacteria living on it. Youre a walking bacteria-covered mess. Just thank the lord that everyone else on this planet is too so you dont have to feel too bad about yourself.
