@lioness Use them whenever you feel the need😊 I'm glad that you found them helpful. I discovered Tai Chi after a Parkinson's diagnosis. It is the one exercise program that been scientifically studied and shown to be helpful to PD patients for range of motion and balance problems. I really think that all folks over 60 have many of the same problems and can be helped by Tai-Chi. If I'm having trouble sleeping or if I wake up in the middle of the night, I've used a video and have been able to get back to sleep. As you can see, I'm a believer.
