Just some strange connections that i have thought of in the shower.
America is the richest country in the world.
On average americans work more hours per week than any other industirled country, maybe there is a conecttion here.
Also, anthor area where there may be a connection is between poor people and TV.
If you are more likley to be overweight when watching large amounts of tv, and you are more likley to be overweight if you are poor. Could it be the TV which makes you poor and obese?
Or do you watch TV because you are poor and obese?
