SITTING DISEASE 12/18

A study finds that on average, Americans spend 56 hours per week sitting, Women's Health Magazine reported. According to the magazine, the "sitting disease is literally killing us." Dr. James Levine of the Mayo Clinic said, "Our bodies have evolved over millions of years to do one thing: move. As human beings, we evolved to stand upright. For thousands of generations, our environment demanded nearly constant physical activity."
