I didn't learn how to type on a typewriter, but it was still considered proper formatting to use two spaces after a period when I went to school, and I used two spaces after a period for a really long time on the internet. I finally got out of the habit awhile back.
I got my first typewriter when i was nine, and started programming when i was 10 back in early 80's. But i didn't formally learn how to type until i had a school subject for it when i was 15. It was the best thing i could possibly have done. By the end of the course i could type error free at 65 words a minute. Now i can type faster than i can speak. I can't recommend it enough.
It's so ingrained for me I probably won't ever stop. Unless I'm on a phone that does automatic spacing. The fact that you stopped to me indicates you probably didn't do it that way for 20 years.
