Do you Live to Eat or Eat to Live?

I went to the movie theaters and asked for a small lemonaid. When the cashier handed it to me I said "sorry this is a large, I asked for a small" She replied that it was a small. It was huge. The large was like a 2 liter. WHY???? This is why America is so obese. Do we live to eat, or eat to live???
I have recently joined the gym about a month ago and started calorie counting. Not only is it the right thing to do, it can make you live longer, avoid disease, decrease tiredness and pain and numbness in legs from poor circulation which is the cause of heart attacks.
