The same way there are people learning how to work with computers, and tablets, peoples with some age already has usually more problems to learn. My father and mother has a phone, but they dont know how to work with computer, and has no interest, this to say im father already even being young i born with a computer near me. There is no age to learn as you wanna or need it, with bitcoin its the same, being knowing more about it or as a extra income bitcoin is a knowhow waiting to be found for anyone.
