THE LONG VIEWThere is an important link to understand between this chapter and chapter 33, on insomnia. I have already mentioned that many energy tonics treat insomnia because increasing chi and blood improves both. What underlies this phenomenon is an important concept: Health is a gradual process. We are easily misled by words. Fatigue and insomnia are real events that took time to develop. Not coincidentally, they also take time to reverse, because the body needs time to heal.
