At the beginning of last night's installment of The Bachelor (season 15, episode 2), host Chris Harrison warns the 20 remaining contestants to, "use your time wisely," a message obviously lost on Melissa (waitress, 32) and Raichel (manscaper ew!, 29), who spent most of their time bitching, fighting, drinking, and crying about one another to bachelor Brad Womack.

This morning on Womack's blog he addressed the drama, saying, "It breaks my heart anytime I see a woman cry and I felt somewhat responsible." Still, in the end, both women were sent packing.

Womack's decision to deny the weepy women a rose is not surprising, especially in light of recent scientific findings on the effect of tears and attraction. Like most animals, humans emit various compounds through body fluids that, once inhaled, communicate subtle signals to those around them. Chemicals present in human sweat have the ability to send a surprising array of emotional cues. Apparently, the same is true of women's tears, which act as a wet blanket on the male libido.

Scientists at Israel's Weizmann Institute asked a group of women to collect tears shed while watching a sad movie on pads that were then given to men to smell while watching images of their faces on a computer screen. While the men could not differentiate between pads with saline and pads with tears, the men tested with feminine "emotional" tears experienced a sharp drop in testosterone--a key hormone in relation to sexual arousal. The tears did not make the men sad or empathetic. But the men who sniffed the tears did rate the faces of women far less attractive than subjects tested with saline.

What this means for us, ladies? In theory, turning on the waterworks to get out of a traffic ticket may have the opposite effect on a male cop. And don't expect a night of epic sex after dragging your man to that epic tearjerker.
