In the spirit of those addictive, you-know-you're-reading-them-even-though-you-wish-you-weren't Facebook notes everywhere, Health.com presents its list of 2 random
things you might not know about the human body, nutrition and exercise, sickness and health. Go ahead. Pass it on to our friends.

1.Dogs can smell cancer and low blood sugar. The Pine Street Foundation, a cancer-education and research center in Calif. published a study showing it was possible to train dogs to identify, based on breath samples, which patients had lung and breast cancer. In diabetics, the presence of ketones -- substances made by the body during the metabolic process -- can be smelled in urine and on the breath when blood sugars are high. Dogs can pick up on other smells that humans can't when glucose levels drop.

2.Researchers at Cornell University found that people who pass through an entryway near the kitchen tend to eat 15 percent more than those who use the front door.

3.Four out of five doctors in the U.K. don't work out enough. Heavy workloads, lack of time and poor motivation contributed to the lack of exercise.

4.You can't get a tan from your computer screen. The Computer Tan Web site was created as a hoax to raise awareness about skin cancer.

5.Baking soda can whiten teeth, and garlic can help treat athlete's foot.
