This is a very interesting study. It took into account what the medical costs of America's inactivity, and invariably obesity, are. It used data from 1995 in order to come up with it's numbers, but the findings are just amazing. The study figures that the final costs of America's inactivity and obesity are 70 billion dollars. I honestly can't even comprehend that much money. That is taking into account a laundry list of illnesses, or comorbidities, of obesity and what it costs to treat these problems. That is a huge amount of money spent to treat everything from sleep apnea and depression to arthritis and heart disease. Pretty much all of these problems can be treated if not cured with weight loss surgery.
