In light of the revelations made during our recent discussion of whether 'tis nobler to wipe standing or sitting, between the legs or reaching around, I’ll ask another hygiene question: Do you use cold water or hot/warm water to brush your teeth?
While getting ready for bed recently I was brushing my pearly whites using cold water, as is my custom. Whem my SO asked what on Earth I was doing I told her that not only was I brought up using cold water, but it made hygienic sense to do so: cold water makes your gums shrink just a bit (other manly body parts shrink as well when exposed to cold water, but that’s another thread)and so more of your tooth’s surface is exposed to the brush. It sounded plausible at the time. She scoffed and said that she have never heard such drivel. Hot water is the way to go for any cleaning job in her book.
OK, then. Which is it?
