Mine too -- I mean, I had domains in 1994-1995.

Most people who have legacy AOL emails have them from more than 25 years ago-- indeed AOL was in decline by 2000.

And "protip: go back in time 30 years ago and tell your kid self how to get a domain name, and navigate internic's overcharging" isn't quite as practical to implement.
