I really enjoy these, Jim. Thank you.

Dozens and dozens of similar examples in medicine - Alzheimer's disease, Epworth scale (for sleep disorders), Hodgkin lymphoma, Foley catheter, Apgar score (health of newborn baby), etc.,

Piggy-backing again :-) In the late 1700's, many houses consisted of a large room with only one chair. Commonly, a long wide board folded down from the wall, and was used for dining. The 'head of the household' always sat in the chair while everyone else ate sitting on the floor. Occasionally a guest, who was usually a man, would be invited to sit in this chair during a meal. To sit in the chair meant you were important and in charge. They called the one sitting in the chair the 'chair man.' Today in business, we use the expression or title 'Chairman' or 'Chairman of the Board..'

Sight for sore eyes A very old expression and means “a very welcome sight,” especially one that is unexpected, such as the sudden appearance of an old friend. The Oxford Dictionary of English Proverbs gives as an example this quotation from a book published in 1836: “What a sight for sore eyes it would be to see Garrick act.” In Jonathan Swift’s “Polite Conversation” (1736) he wrote: The sight of you is good for sore eyes.”
