Yes.
Actually, I had never heard of Tolkien until I was an adult; actually, more accurately, I had never heard of him until I was a graduate. Then, some of the nerdish guys (it is always guys) I used to socialise with in college (and elsewhere) recommended him highly (as in 'you haven't lived until you've read this' type of recommendation). One chap insisted that I start with 'The Hobbit' and then proceed to TLOTR. I did. Three times, cover to cover, over the past (um, few) decades, most recently when I had a bad cold some years ago and spent a week in bed. And that is it.
Another very good friend of mine, who holds a senior position with my country's Finance Ministry (a career public servant) spends a surprising amount of time each and every Christmas re-reading TLOTR. Personally, I draw the line at that.......
