Ha! I knew someone would back me on this. I have forever maintained that if a book isn't working for me by page fifty then it's a goner. No guilt. No regrets. Life, really, is just too short to be wasting my cranial power trying to figure out bad prose, uninspired scenes, and witless characters. This article even goes on to suggest that after one reaches the age of 50 one is invited to subtract their age from 100 and use that number as the number of pages after which one is allowed to quit a book. So someone at age 63, say, can give a book 37 pages before deciding if it's worth sticking with or not, and so on. And if you reach 100 years of age? Well then, by golly, you have earned the right to tell a book by its cover.
