Definitely don’t put grease or oil down the drain if it is solid at room temperature. Even oil that’s liquid at room temperature is bad for sewage systems - they combine with non-biodegradable sewage waste such as wet-wipes (Don’t flush wet wipes down the toilet. Put them in the trash.) and turn into rocks that narrow and block the sewage pipes. See wiki on Fatbergs https://en.m.wikipedia.org/wiki/Fatberg
I try to name unconnected things until I’m interrupted by a different thought, then when I realize I’ve gone off I play the unconnected naming game again. Doesn’t matter if there is a connection. Apparently this disorganized thinking is similar to sleep thoughts and can help get your brain in the mood for sleeping.
Example: sheep, glass, shelf, sock, alien, whisker, etc
