15 years ago, when computers were less ubiquitous than today, I worked with near-retirement-age users (many 55 or 60 yrs old) who had NEVER used a computer (I had to start by teaching how to move a mouse). And they were perfectly trainable as long as you didn't start with an attitude that they were dumb for not already knowing this stuff.

My father's pleasure is to spend half an hour a day on Windows Solitaire. He moves the cards faster than I can see what the cards are... It took him probably a week to accommodate with the mouse and now he is faster than anyone I know. My guess is that if he knew a little bit of English he would have entered "that Internet of yours" with no difficulties. He is technical literate mind you - he build in the early 90s a Spectrum clone.

On the other hand I see plenty of 25+ people that don't care too much to change their status quo. I might as well be one of them and pretend I'm not.
