I agree that people of all ages should read books from all periods of literature to learn more about different time periods and how people lived then. This is especially important now, with so much focus on tech these days. This is one reason I chose to write a book set in the 1980s. This was the decade in which I grew up, so I know a lot about it. I now hope others will learn more about it if my book ever comes to fruition.
And if I had ever had children, I try to get them to read books I'd loved as a child, or even read those books to them.
