And all the exercise he gets! I saw a scientific study where they analyzed a person's skin cells. They had a group of people randomly assigned to exercise 3 days a week for 90 days. After 90 days the skin cells of those who exercised looked younger under the microscope than those who didn't (can't remember what markers they were looking at, but I specifically remember they used skin from the subjects butts to make sure what they observed wasn't related to sun exposure).
