Interesting. As an aside I read that running a marathon would burn about a pound of fat.

You get ear and eye infections from parasites I believe, often from waterfowl. So it depends on where and when.

It takes a lot more exercize to burn food off than people think, especially to burn fat off.

Few will get enough exercize to make up for overeating junk food.

Learn to fill up on veggies, fruit, eat whole grains, unprocessed food, and moderate exercize is enough to stay moderately not a fat bastard.
