[Internet] is still just over 25 years old.

Internet is more than 40 years old already for what it's worth. Internet came to Norwegian universities around 1978. I'm not sure when my mother started using it, but I would guess around 1980 ... I should probably ask her about that. I believe it was around 1990 I got access to FIdonet, and we did have some gateways to email and Usenet though they rarely worked.
