>In archaic usage, the vapours (or vapors) is a mental, psychological, or physical state,[1] such as hysteria, mania, clinical depression, bipolar disorder, lightheadedness, fainting, flush, withdrawal syndrome, mood swings, or PMS in which a sufferer loses mental focus. Ascribed primarily to women and thought to be caused by internal emanations (vapours) from the womb, it was related to the concept of female hysteria. The word "vapours" was subsequently used to describe a depressed or hysterical nervous condition
heh, medicine really had no idea what the fuck was with women for a long time
