I also do Sudoku as a test of my brain function. I complete the daily puzzle slower, enter the wrong number into a cell (not the number I repeat in my brain), or count on my fingers.

I use to do Word Search, Jigsaw Puzzles, and other brain function games each morning prior to Covid. I would see how fast I could complete each game.

Post Covid, I have dropped down to 2 games, because I began having high anxiety just trying to do the games. I noticed my brain was not operating like it use to.
