The first time I was given a book on the Rules of Golf, I was an enthusiastic teenager playing golf two to three times a week. The book was an inch and a half thick and contained 562 pages. Was I going to read it? Absolutely not. If I was going to get Repetitive Strain Injury it was going to be from swinging my clubs, not from turning hundreds of pages.
