The only Mowat book I have read is Never Cry Wolf, which I found fascinating at the time. I may have to look for more of his.
My dad had an 8th grade education, and he was a good reader, but only of newspapers, magazines and practical books. Novels held no interest. My mother loved to read, especially novels, and late in her life she discovered mysteries. My two sisters and I are all readers. My mother read to us when we were small. We received books for gifts, and were encouraged to read. All 3 of my children, adults now, read for pleasure as well as for school or work.
When I was young, I collected all the Perry Mason paperbacks. I had a big box full, which I forgot about and left with my parents. My Mom kept them for me, for years, and finally asked if she could sell them at a garage sale. I think now that she read them all first.
My husband is also a reader. His mother, who is 90, still enjoys word puzzles, although she no longer reads books. She was a prolific reader until a few years ago, when she just lost interest. I'm thinking her eyes got tired.
