Time of the month
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; if she is menstruating or menopausal, she
tends to be more attracted to a man with scissors lodged in his temple
and duct tape over his mouth while he is on fire.
No further studies are expected.
