Are your humors in balance?

For those of you who don't know what the four humors are, they were conceived in Aristotle's time and continued to be the widely held belief regarding physical health up until the advent of modern science in the 19th Century. According to the four humors theory a person is healthy if their humors--black bile, phlegm, yellow bile and blood--are in balance. Diseases were thought to be caused by an excess or deficit of one or more of the humors. In the Muslim religion "black pions" were thought to stem from someone having too much black bile.
