I know what your talking about on here Von many different people now days, glad to see your still first class in what you do . Age has a way of changing how we do things more and more I have 2 knees that need replacing and just waiting as long as possible and adjusting how I do things , take care of your body when your younger so things don't wear out prematurely . If we can help someone out by all means do so try not to criticize the world does enough of that.
