jealousy

It's refreshing to run across new studies like this one from Pennsylvania State University that poke holes in the kneejerk theory that in relationships, men are ultimately motivated by sex and women live for love. That idea especially came up while Molly and I were researching for our episode on whether men and women cheat for different reasons. Time and again, the studies seemed to condense women down to soul mate-seekers straight out of Debra Messing movies, while the men play sex-hungry beasts.

Shakespeare referred to jealousy as a "green-eyed monster," a beastly emotion that brings out the worst in us. But why do we feel jealous? Are women more jealous than men? Find out how jealousy works in this podcast from HowStuffWorks.com.
