In the olden days people were called"Chairman" or "Chairwoman". Today, all over the place people are called "Chair" as in: "He is Chair of the Philosophy department".
Why are we calling human beings by the name of a piece of furniture?
And is it worth it to be the head of ANYTHING if it means that people are going to sit on you?
כי בצלם אלקים ברא האדם.
