The skinny on affairs

From MSN.com :

If you're worried your guy might cheat, try checking out his waistline. A new study says the size of his belly may reveal whether he'll stray.

Even the tiniest suspicion that her man might be unfaithful can turn some women into an investigator worthy of a guest-starring role on CSI. Now, a surprising new study suggests that women with huskier mates can breathe a bit easier on this front.

Here's the scoop: When researchers surveyed 1,000 men, 23% of average-sized guys and 19% of moderately overweight men said they'd cheat on their partners if they had the chance. However, only 11% of very overweight men said they'd stray. "The more you weigh, the less interested you are in sexual dalliances," said men's health expert Sascha Rusch of the health institute Epicure, which commissioned the study.
