Man, I am not even sure what to say about tai chi. It's changed my awareness of my body, if that makes any sense, and after years and years of dance and martial arts it's not like I wasn't aware of it to begin with. It's corrected the way I walk so that I find I have far less knee and back pain; it helps, in some bizarre way I can't explain, the tendinitis in my wrists. I can balance on one foot with my eyes closed! Harder than one might think. Idk, this all seems really vague, but in conclusion: it makes my body work better.

Weight loss: I lost about 70lbs ummm...almost ten years ago? Eight? Something like that. Part of it was kung fu, which is what I was taking then, before tai chi. Part of it was cutting out dairy, corn, and most soy due to food sensitivities. The rest? I am honestly not sure. I'm just happy I haven't had a problem keeping it off. Sorry, I know that wasn't terribly clear, and you're welcome to ask questions if you want. :)
