Age has nothing to do with it. 90 year old people with us make puzzles (which are games), they play memory and word games and do cross word puzzles to keep the brain active. There are also who play cards or games where knowledge questions should be answered. And there is chess and there are many more games. We don't have to play in groups or join competitions. I like to relax and think it bit which I can if I focus on Sudoku or a mind game. It doesn't have to take hours and I can also finish it next day or week just how I feel.

Friend you are not 90+ years old yet and it's good to relax.
