Learn to knit or crochet. There is loom knitting which is repetitive but you could make knit hats for a hospital that treats cancer patients. A lot of times they have a basket for patients to pick a cap or caps. Due to hair loss during their treatments. These looms are round plastic and it seems you keep looping the yarn over pegs and then use a hook and join the next loop together. I have thought about doing it myself. You could make them for the homeless too.
My hub does word search puzzles. I do on line solitaire or on line checkers. It is a time sink and challenging to try to beat the computer.

Read up on history. I used to despise history in school. Now I find it totally amazing to think what people did a few hundred years ago like explorers going to the Antarctic, pioneers blazing a trail to the west in horse wagons. They had none of the modern conveniences that we take for granted, had no GPS, had no gas stations to get a broken wheel fixed, no computers or cell phones to look things up. No grocery stores that have an abundance of every imaginable food.
