Query: A good book

This is the second book im reading about the WWII period (although this book doesnt take place specifically during WWII) and its truly amazing what people can do. Sure, people think that he might be making things up because a. how does he remember all these things specifically? and b. how can a person really go that long without water? Well, answering question a, if you go through something so life changing, its not going to just escape your memory. Yeah, I agree that maybe he might be exaggerating the number of days he went without water in the Gobi, but a majority of this story really does have to be true. As for the spotting of the Yeti, we just might never know....
