Medicinal words to describe people

My three children went to a Waldorf school. Waldorf uses the temperaments as one of its many child-management tools. For instance, children of like temperament are often seated together, so that they can "see themselves" and develop accordingly. It works better to have a choleric kid bumping heads with another choleric kid instead of with a weepy melancholic. The phlegs bore one another into action. The melans get fed up with one another's whining. The
sanguines have to learn to tamp down the chatter to get anything done.

My children are: Phlegmatic, Melancholic, and Sanguine-Choleric, so I got to experience four temperaments in three kids. Deciding what to do on a family outing was an interesting experience, I can tell you. - Laura Kennedy q.awad
