Query: The BEST T'ai chi video EVER!

This is a wonderful video -- easy to follow with great explanations and something other t'ai chi videos don't have -- humor! Dr. Keith Jeffery is a very witty guy and his humor really helps one learn the simple, yet effective, t'ai chi moves. This video also has great scenes of wildlife in action that serve to illustrate the origin of the often odd t'ai chi names. Keith performs the t'ai chi moves in gorgeous British Columbia settings, as well as in a well-designed studio setting with a mirror to help the student view his movements from front and back. I have eight t'ai chi videos; this is the best of the bunch and the only one I view/do on a regular basis. Buy it!
