Most people in the US are fat while others go hungry. Fat people don't exercise because it hurts their knees, backs, etc. They are also usually depressed about their bodies so don't do much other than eat to ease their pain. This is a dangerous cycle that severely limits their ability to learn, grow, and achieve their full potential as a productive member of society. It also drastically raises medical costs as they take pain medication along with anxiety or depression medication. Ultimately their medical bills are much more expensive due to heart attack, stroke, etc and we all have to pay for that. We could save a lot of money as a community and a nation if people start taking care of themselves by exercising and eating right.
