Sunny days I can usually dodge people on the sidewalks okay without it. Reading in any normal fashion is out of the question. And I need help getting around in restaurants, bars, or any unfamiliar environment. Without it, I usually just end up looking drunk. And whether or not I WAS drunk at the time is beside the point.
Medical research is a funny animal that way.
A mountain of research cash is funneled towards one disease, cancer, AIDS, whatever, while others fall by the wayside. A few years later, attention shifts for whatever reason, and the money s redirected towards another disease. Over the past few years, it seems, research into RDs has been going great guns. So in short, no, I think word is getting around, and has for the last several years. Oh, I ve no doubt that a cure will be found eventually.
