This is key. Everything else is an excuse.

My Mum is in her 70s and until she lost feeling in one of her hands (chemotherapy 23-ish years ago) she was an exceedingly fast touch typist. Even without feeling in her hands, she could still type at ~40 WPM, possibly higher depending on what she was typing. Arthritis means she now mostly uses a tablet.

But looking at other people in that age range, I can think of literally zero from church who even know how to touch type. It's probably the difference between someone who had to do secretarial work and someone who did not.

I do think your first statement is absolutely on the mark. e.g., "I'm old, and I don't understand it, so I won't try."

The old adage is still true: Whether you think you can or you can't you're probably right.
