Our society (in teh U.S.A) has enabled the obese by way of technology.
Thanks to computers, GPS, elevators, escalators, television, TV changers, delivery boys, drive throught, cell phones, mass transit, 3 wheel Wal Mart fatty carts, etc.. the fatties can go day after day, month after month, year after year without ever physically exerting themselves. They can even pick up their scripts at a drive through pharmacy.
An intelligent, technologically advance country has destined the fatties to morbid fatness. Is that irony?
