Not that many years ago I was laying in bed reading The Tale of Genjii when a sharp jabbing pain in my wrist caused me to yelp, drop the book on my exposed nose, and lose my place amid all those exciting medieval pages. Surely something had snapped in my overstressed wrist and I was forced to prop-up all my big fat reading from that point on.
Another change in my reading life caused by this event was a tendency to eschew my beloved big fat books in favor of more safety minded slim titles.
I guess I got out of the habit and I have been shifting the big ones back to the bottom of the reading pile for several years now. I might have blamed my dimming eyes but I think it was more my aging patience: Why read one big one when you can read a half-dozen that are possibly just as good, albeit much thinner.
