Part 1 of the book goes into the nuances and details of becoming a skier, either in the resorts or in the mountains. Most skiers are probably going to need part 2 of the book, if they ski hard enough and long enough. The author shares a myriad of mistakes made as well as misadventures skiing in the resorts and in the mountains, lessons hard won and invaluable for any aspiring skier. Part 2 summarizes knowledge gained over the span of 4 decades of private practice about how knees get injured, what hurts them, and how to heal them, what to be careful about, and how to enjoy a lifetime of strong legs and knees.
