If you're over 35ish then this question probably isn't relevant to you so why would you open the thread and say you didn't have one instead of just ignoring it?
Wow.
I might not have had an email address but in VI form I was using a network of computers, knew about ARPANET and JANET.
In my first proper job in 1985/6ish I didn't have an e-mail address but we did have a fore runner and could message other branches.
Ladies the cringe teenage emails are still a thing, part of my 'applying to UCAS' talk includes using your college email not 'sexysussielikes...' even if you never check it, start checking it and using it.
Some of my friends had access to CB radio envy they had 'handles', it all seemed very exciting.I imagine they were talking to truck drivers.
Nope we were mostly talking to other teens, the truck drivers would occasionally ask us to go meet them but we were more concerned with school, make up, arranging to go out etc.
Email didn't exists when I was a teenager. In fact the Internet didn't exist. Not sure computers existed outside of NASA.
Babbage described the ' Analytical Engine' and 'Difference' engine in the 1800s, Ada Lovelace wrote the first program in 1843, I doubt you are that old.
