True, but I don't think Calvin Ball rewards the brain as much as YouTube or video games (a personal take of course). Loads of people of all ages are "suffering" from shortened attention spans with YouTube, TikTok, games, etc. but I haven't heard of any having the same with Calvin Ball.

I do miss me some Calvin Ball though.

We used to call it "Superman" in the late 1970s and I thought it was no fun at all.
