Back in the 90s I joined a ham radio club, computers were already a big thing in that community, which
was mostly 50, 60 and 70 year olds. Most of the members were very computer literate. I have breakfast a couple times a week with several of them, two of them in their upper 70s continue to stay updated and can out do me any day on computer use, program installation, programing Excel, etc.
They are my goto when I need computer help.
The computer I'm using was built with the exact components one of the 70 years olds decided to use when he built his computer. I need to talk him into building a later version, this one is just a weeks shy of it 9th birthday.
