Man O man do I remember those "black out" covers for the keys back in the 1950's. That was hell, but it taught me not to look at the keyboard. I too, was one of the only boys in my typing class, but it started out as a reason to sit by my main squeeze in typing class.
I used it sparingly in college and medical school. Later, when electronic medical records came along, just before I retired, I was one of the few docs in our hospital that could type. Now all of the college and medical school students type 60+ words a minute, or the can't keep up. I only wish that i had kept up my skills. It has been complicated by losing the end of my left index finger in a woodworking accident. After 28 years ago today, the accident has left the tip of my finger sensitive and the shortness is also a complication. I predict that typing instruction will begin in elementary school in the near future.
