I did tai chi for three months at an excellent studio way way back. In the book I am reading on surviving mental health issues like mine, they recommend it. There is a new YMCA that will open in January in this burb. There is also a martial arts school nearby which may offer tai chi. It would be a great way to meet new people as well. 

Now that I dont smoke pot, I also smoke easily way less cigarettes (a third less).
