I have always had trouble walking for long distances without being short of breath. My wife is an avid walker and when we would take walks together I was always trying to stay up with her. After one month of using the Theralumen device for 15 minutes a day she asked me to take a walk with her. To my great surprise and astonishment we walked at a very brisk pace for two miles and I wasn’t even out of breath. We talked the whole way and when we were finished I had trouble believing what had just happened. Two days later we took another walk with the same results. I must admit I am completely astonished at the difference. Thank you for such a simple and effective answer to a lifelong problem.
