Re-think: Your fitness

Last night I saw an add from a magazine and on one side of the page it had this long paragraph saying blah blah blah about what ever the add was for. On the other side of the page it just said "Re-think" in big colorful letters on a black page. This immediately sparked something. America has more overweight people in it's population then it has healthy people. More then half of the people in our country are overweight. More then half the people are not healthy due to weight problems. Mcdonald's claims to serve 75 hamburgers per second. Yea they said that, not me.
So basically my question is this: Why don't we "Re-think" that? Why don't we "Re-think" what we eat and do?? Why don't we as a country "Re-think" the fact that our population is overweight??

 Why don't we "Re-think" our fitness??
