I read somewhere, recently, that the average was one book a year. I don’t know anyone who only read one book.
I read around 250 books in 2003 but admittedly I read fast. If I read a mystery or popular fiction I generally read it in one sitting. Exceptions: Annie Dillard, Diana Gabaldon, Tom Wolf, and the odd gigantic book like A Suitable Boy which I did not read last year but, the year I read it, I had to recheck it. The Lovely Bones took a little under two hours.
I don’t count as reading books on tape which I “read” in the car.
I think those who read a lot (IMO, over 100 books/year) should be commended.
OTOH, my parents knew a husband/wife couple with whom they socialized when they were younger. This pair read books, books, books all the time. They would go on a trip together somewhere, and these two would stay in their hotel room, reading books. When they went out, it was to go shopping at … you guessed it … a bookstore. They had read EVERYTHING (my brothers and I even tested them about these really obscure - we thought - books, and they said they had read all of them).
Suffice it to say that eventually, my parents ended their relationship. Like any other activity, I suppose, reading can be an obsession which gets in the way of other pursuits.
But keep reading, y’all!
