I am an elderly man and it is hard for me to do everything that I used to do when I was younger. I still want to have a sense that I can take care of myself and take care of my daily needs as well. The Onyx 9500 is one way in which I am able to keep a grasp on my health and stay away from danger. I have asthma and sometimes it is hard for me to realize when I need to take it easy. By getting results from the Onyx consistently I am able to take care of myself better.
