I remember the first computer my family bought that had a modem. The internet was a novelty and because it tied up your phone line you had to be careful when you used it (lest you miss out on a call). No mobile phones also meant that solo activities were limited to what these scientists listed: reading, writing, drawing, etc... BUT, I had access to my friends. I could go out and play basketball, run around on the play-gym playing tag, and just walking around town.

It's no wonder that these kids had anxiety! Forced solitude is brutal.
