I have bad memory at times. Mostly concerned when I forget something I know well. The other day I forgot the word "distributed system",which I use a lot. Felt embarrassing. I noticed it's way worse when I don't sleep. I have serious dust mites allergy, I wonder if that has a great effect (my nose is always partially blocked). When I code I work well, I seem to remember a lot of details, to the point it surprises me.
