My father was 75 when his finances had deteriorated to the point where he was no longer able to afford a personal secretary.

He had me explain the things he had to do, and he wrote them down on paper, step by step. He was pretty quickly able to do all the things he needed to do on his desktop.

Never got fast typing down, so I got him dictation software. Anyway, I’m pretty convinced as long as your determined, you can stay hip to new technology in a way that at least allows you to work with it.
