I don't think there is a maximum age. My Dad played NES, Sega Genesis, PS1, and PS2 with me. If everybody followed your idea TC, he would've stopped at NES with me. Those were some of my best childhood memories and I want to give the same to my future children. If games weigh anyone down, it's because they let the game weigh them down. I, on the other hand, know how to put the controller down and go outside. I've played video games for the 24 years I've been alive and was always able to do that.
