Gotta take up for Yamcha here. The post was a joke. There are lots of variations on this one. There's the "blackmail diet" for instance. You put a large sum of money in a trust with a lawyer. If you don't lose a specified amount of weight in a given time, the money is donated to the American Nazi party.
Yur all just prickly because of the previous post on how exercise is making us all old and saggy, which BTW seems to be absolutely true. We are all really saggy and pale and we all need a nap.
