I have a friend of mine (married about 40 years) who he and his wife sit down every night and study Tehillim (using the ArtScroll 2 volume set by R’ Avrahom Chaim Feuer).
If you have internet access you may want to look into the shiurim on Torahanytime dot com. You can sit and listen and then discuss what you have just listened to.
My father A”H used to put together jigsaw puzzles.
