I had an acupuncture treatment today. I recently began getting it for a variety of reasons; despite being a huge needle-phobe, I'm fascinated with this treatment's stellar track record for so many different things, not to mention how long it's been making people feel better - just like yoga. Again from Wikipedia: "Symptoms of various illnesses are often believed to be the product of disrupted, blocked, or unbalanced chi movement (interrupted flow) through the body...Traditional Chinese medicine often seeks to relieve these imbalances by adjusting the circulation of chi." Acupuncture is truly like no other experience I have had - you can actually feel tingling sensations and different parts of your body awakening (parts that don't necessarily have needles in them) - they say that's the energy starting to flow properly again. And for you skeptics, there is quite a science to it - training to become an acupuncturist is as intense and long as medical school.
So, I've got my yoga practice to get my prana flowing, and acupuncture to balance my chi. I like the idea of tapping into health care systems that have existed for thousands of years.
