It is not about age, it is about listening, and not listening to only one thing/person, but listening to anybody, not intercepting the talk, just take it in and think about why that person is saying what they saying how, don’t blame them for saying something “illogical” in your view, try to find reason in it by asking clever questions that do not insult the other person.
If you manage to do so, you can understand why what is and how it is, by talking to enough people, age is irrelevant.
