Some have said here that my use of the term "co-chair" or "chair" is incorrect, and that "chair" refers only to the office and not to its occupant. Though that may have been true at one time, I believe the usage is changing; I can find evidence on-line from reliable sources for both sides of the argument.

To Ebbie re "nurse": Hmmm, seems that we're both seeing what we want to see and calling it "obvious"! My perception is that the noun "nurse" has its origins in the verb "nurse" (to suckle) -- a nurse was nourishing another woman's baby which, during the time that the word originated, would have to have meant suckling that baby at the other woman's breast. I dispute your argument that the distinction between "wet nurse" and "dry nurse" means that the origin of the word "nurse" did not have to do with suckling; I would think that the distinction arose after the invention of the baby bottle!
