If increased understanding is facilitated by coming across the same idea(s) in contrasting contexts then the old have an advantage over the young in simply having come across more contexts. Another advantage is gaining time for these contexts through needing less sleep. I found myself up earlier than reasonable today and decided to catch up with a burgeoning archive of radio recordings.

1/3 of young rarely people spend time with adult relations but 90% of those who do report that they enjoy it
In conjunction with the above points, the solution for all ages seems obvious – the implementation, less so.
