My peers are college age students and the people I chat with on IRC (who I happen to know are mostly young, college age adults because of the demographics of the fandom that the IRC channel I frequent was created for).
I certainly reply faster than most others who use the channel. My replies contain more words and characters and usually have correct spelling, punctuation, and grammar. In most cases I can get out a grammatically correct, spelling-error free, and properly punctuated short reply faster than other people replying to the same comment with sentence fragments.
The people on the IRC I compete with in the arena of fast and tidy replies are the people who I happen to know are well into their thirties and forties, and are also heavy computer users. E.g. at least one professional writer, a computer engineer, and a professional librarian. Co-incidentally, the engineer and the librarian are both fathers with middle-school aged children.
I learned to touch type on a qwerty keyboard by playing UT2004, not having a microphone, and wanting to chat a lot. I had a personal rule that I would only use full sentences. I played that way for a few years.
It's been a while, but the last time I used a WPM test I was rated somewhere around 50 wpm. I am almost certainly remembering that wrong but I can't be arsed to go take another test.
