Playing video games may improve your eyesight and some aspects of thinking, even enlarging parts of the brain:
This reminds me of something I read many years ago. Men typically do better than women in tests of spacial reasoning, but when women play video games the difference largely disappears.
The same folks have a video on the dangers of sitting and spending too much time indoors. (Something I’ve heard a lot lately and keep thinking about because I’m way too guilty of both.) Maybe I need to get one of the game consoles that requires moving the whole body to interact. That would at least help with the sitting.
