You may wonder why some people get sick while others do not. Those that tend towards sickness most likely have some internal deficiencies or imbalances.
The specifics are difficult to explain and one of the many reasons for all of my education and training! Basically, a certain substance in the body is either not able to fulfill all of its functions or the external pathogenic invader is really strong. If the EPI is strong, but the right qi of the body (part of the body’s defense) is also strong, the person tend to not get sick as often. If the EPI is strong but the right qi is deficient, the person tends to get sick.
