I already have that superpower I once used lots of letters so that if you read the for loops top to bottom the letters spelt out my name and a message.
I also once heard that wether you use "a" or "i" depends on if you came from a mathematical or engineering background.
What's really stange (for me) is in C and PHP; I use "i". But in Pascal, and Python ; I use "a". I know that to a certain extent it is muscle memory since if I use "i" in Pascal, I nearly always leave out the colon before the equal sign. Maybe it's a coping mechanism because I switch between languages so much.
