Live Long, Live Well: Teachings from the Chinese Nourishment of Life Tradition – by Peter Deadman.
If someone ever asks you what are the proven benefits of regular Tai Chi Chuan or Qigong practice maybe you could try the following sentence ...
“Either Tai Chi or Qigong have been shown to improve renal and cardiac function in kidney and heart disease patients, improve lung function, reduce blood pressure, reduce inflammatory markers in the blood, benefit metabolic syndrome, help diabetic neuropathy, improve the symptoms of multiple sclerosis, improve chronic fatigue, reduce fatigue in cancer sufferers, reduce cancer therapy side-effects, increase testosterone, improve sleep, reduce prenatal depression, reduce stress, improve attention in young adults and cognitive function in elders, restructure the brain, delay cognitive decline help overcome addiction to substance abuse, improve exercise capacity, help Parkinson’s disease patients to improve balance and reduce falling, benefit knee arthritis, improve rheumatoid arthritis, promote arterial flexibility and muscle strength, reduce lower back pain and disability, improve ankylosing spondylitis, and much more.”
Or, if that is too much of a mouthful, maybe you could just say that it makes you feel good, and you practice it regardless of the benefits. (I got stuck on the words “and much more”).
For those who are curious and interested, Peter’s book is a good read. (Thanks to Dr Carl Muller for pointing me in this direction.)
A more detailed review of Tai Chi research and some of the science behind its benefits can be found in "The Harvard Medical School Guide to Tai Chi". (Simply Google for copies to buy, or read an on-line version here).
