How to find youngsters to help seniors?

Our original idea was that old people have some young ones around within their family.
Unfortunately it is quite rare. We know all the reasons.
Actually it was the same with me in the beginning. With Basic Language it was OK. But when it came to more sophisticated usage, methods, I joined every course that was around.
Still... there are new devices, new methods all the time. It's not easy to keep up with actual ways.
