There is a third belief in medicine. The combination of therapies. I will agree stress is a killer. That also includes the lack of sleep or regeneration time. How that is accomplished is another matter. Drugs vs meditation etc. or even natural supplements. Some of the alternative therapies are being accepted. Also, the use of drugs have side effects. That also goes for natural supplements and alternative therapies.
I did have a session of acupunctures. During that session, I felt a ball of energy. I sort of directed it around a bit. Then it slipped done my left leg. It sort of went to sleep on me. Yeah, a bit strange. I went dancing that night, but only a few dances, and nothing stressful. The next morning my left knee was twice the size of my right.
