As an adamant Tai Chi goer, I think people should be doing Tai Chi multiple times a week, if not everyday. However I understand that not all people grew up being introduced to activities like this and need some encouragement. It really helps to calm nerves and release stress. On top of that you feel very connected to your body and the other people around you.
So, Boston Tai Chi is holding a free introductory class. It's ideal for all ages and fitness levels. This really is an activity/exercise that can improve ANYONE'S life.
