People don't stop living when they turn 80, nor does the body stop healing.
When working with someone using Spring Forest Qigong, healing is happening at a lot of different levels. Can there be a point at which the body may not be able to totally correct itself? Yes. Do you still work with them? Yes.
The healing, while not being taken on entirely at the physical level is happening at a mental, emotional, and spiritual level. That healing makes a
big difference for them, so don't over look the opportunity.
As for the tinnitus, work sword fingers on the ears. Sword finger and build energy in the kidneys. Rub you hands warm and palm the ears while tapping 3-4 times the base of the head with one index finger, then the next for a couple minutes.
Most is about what your willing to spend time and energy on. Chunyi had a master that focused on having a second eye lid like Europeans have, and made it happen. Like Chunyi would say. Anything is possible.
Much Love, Shawn
