I have been typing ever since I was 13 years old. Back when I was in school, typing on a manual typewriter was actually offered as an elective course, which I took at 15. It amazes me that I have been typing all these years, and yet there are still inconsistencies with my speed. Depending on the kind of week I am having, sometimes I can type 130 words per minute, and other weeks I'm lucky to get 80. I still haven't quite figured this out after 40 years!
