In response to the most recent posting of my friend, Pigassus, I have to agree that your suggestion not only sounds like fun, but would most certainly result in significant weight loss. There's only one problem. NO ONE wants to get caught in flagrante delicto with a fat woman.
So I have to keep walking. It's my only hope.

P. S. - Dearest Pigassus,
You could watch TV while you're walking on the treadmill. That's what I do.
