I am 59 and was slouching badly. I thought that if I didn’t take some action now, it would be permanent and would hamper my breathing. I was wearing it too long at first and my shoulders hurt. I slowly broke it in and am very happy with the results. I am standing up straighter even when I don’t have it on. I can now wear it all day long. I even wear it to the gym. Be sure to loosen the straps a lot. It makes it easier to put on and take off. Even when I don’t have it on, I no longer slouch.
