I'm a yoga instructor in my town and I've a new wave of business ever since PBS did a special on yoga's history as both a physical practice and a spiritual one.
Ive always wanted to try yoga, seems nice and relaxing.
The stretches in yoga are a great way to spiritually calm the mind, especially once you can do them without much phsyical straining.
Yea it seems like it would help loosen you up a lot
Although I do caution that it isn't some kind of new exotic Eastern religion or something.  Some of the earliest "gurus" in the West had a tendency to go overboard a bit.
Yea its common among things that originate in India
But, regardless, we can discard that stuff and focus on yoga as a great low impact exercise regimen.
yea Ill give it a try sometime in the future.
