I've reached the stage of incompetency where if I can remember what a logarithm IS, It's a good day, and if I can remember why you use them it's a stellar day. I'd put it on a tee shirt but I have to work out which is the skinside and which is the outside first. Used to be the seams and fruit-of-the-loom/union-made label told you but now people wear seams as a badge of pride and labels are outré
