Everyone has interests or hobbies and it is that point a lone that I can say anyone can learn computers. At the same time, the hobby or interest must have some kind of structure and or hierarchy of management. Take an engine for example. You have the key, that turns over the starter, to allow power from the battery to start your car. There is more to it than that, but you could explain a computer to a mechanic in the same fashion. My point that I am getting at is anyone can learn a computer when you relate it to something that they understand.
Did you ever see the movie “RoadTrip“? In the movie a character has to study for a philosophy test and has less than 18 hours to do so. So Paulo Costanzo explains to Breckin Meyer how the philosophy works by relating everything in wrestling (WWF at the time) terms. Take the movie “The Sandlot” as another example. Tom Guiry doesn’t know how to throw a baseball and so Mike Vitar explains it to him as if he was throwing papers on a paper route from a moving car.
You can relate anything to anyone if you and the other person have at least one common interest.
