Query: Very Good Read

I enjoyed this book, which I read a few years after beginning my airline career. The author gives very good advice on health and nutrition, not to mention avoiding viruses and disease. The author also touches on fatigue while flying, sleep deprivation and jet lag, not to mention stress relief. A very interesting and thought-provoking read. I recommend it for airline crewmembers.
