Are you smarter than a 5th grader?  That's been done on TV.  Now the question is, are you fitter than a 15 year old?  Today's report in Men's Health challenges the question and according to German researchers, the answer is no.

The test occurred when they put 8,000 German students ages 10 to 25 for running speeds and chin-up strength.  BMI and smoking habits were factored in.  The results put the 15 year olds ahead of the 25 year olds.

The results showed that the older you get, the more out of shape you get, unless you "put your health first in your 20's."  The truth is the older you get, the less time you have to stay fit unless you schedule it in your day like anything else you do in a given day.
