It's been around but I received this from Jimmy at The Barnacle and it always makes me laugh...
A study worth sharing with friends both male and female:
A study conducted by UCLA's Department of Psychiatry has revealed that the kind of face a woman finds attractive on a man can differ depending on where she is in her menstrual cycle. For example: if she is ovulating, she is attracted to men with rugged and masculine features. However, if she is menstruating or menopausal, she tends to be more attracted to a man with duct tape over his mouth and a spear lodged in his chest with a bat up his ass while he is on fire.
No further studies are expected on this subject
