I think what’s more interesting from those charts isn’t just the divergence between genders - it’s that (with the obvious exception of S Korea - what on earth is going on in that country??) men’s attitudes have slightly trended more conservative whereas women’s attitudes have radically changed to more liberal.
Can confirm - my husband and I started reading to each other years ago. It’s not all the time, maybe a couple of books a year, but always on holiday - it’s an awesome way to be together rather than each stuck into your own book world.
Would recommend!
