I have osteoporosis and I think Dahn Yoga is really helping me. At my last doctor's visit I found out I had gained 3/4 inch in height. My posture has improved and I feel so much better. Also, I had been diagnosed with a heart murmur and recommended to have an echo test every year. Yesterday, my cardiologist listened to my heart and said I did not need the test; he couldn't hear anything!
