4%? That's it?! If you think of all the wasted time watching TV, playing on the computer, socializing (however, socializing is my middle name, so don't skip this one!), but 4-5 days a week we can all certainly find 45 minutes to an hour to boost those endorphins, and keep healthy! Notice I said "keep healthy" and not get fit, or look good in that bathing suit? As we get older, getting healthy and staying healthy should be our number one priority! There's too many diseases out there trying to bring us all down, but the first step to warding these evil diseases off........ workout and eat healthy. No excuses!
