Hysteria
and Hysterectomy both come from the word 'hystera'.
Why?
Because, ancient Greeks believed that women would become mentally unsound if their uterus travelled up their the tube that connected their two 'mouths' towards their neck.
How did they cure this?
One cure was to make the woman stand over burning myrrh; the sweet smell coaxing the womb back into place.
Has anyone nearly thrown up in a lecture?
