Likewise, through Middle School., High School. University, and my first three-and-a-half year work experience in China, I read incessantly. I probably averaged two or three books per month (typically nonfiction, initially popular science but increasingly technical, with several textbooks of various subjects thrown in for good measure) for... about fourteen years. That leads me to estimate about 420 books in that period, which roughly matches with the size of my “read” bookcase.
