From the helpful folks who brought you the Home Shopping Network comes this continuing home medical-testing program. Easy and convenient for the go-getter, the single parent, or the older viewer, "This Old Lung" creatively utilizes your TV's own radiation to conduct a wide variety of simple but important medical procedures. This week, we'll be checking for brain lesions. Just stop by your local Walgreens, Safeway, or 7-Eleven and pick up a set of official "This Old Lung" mail-in TV X rays (they come in a variety of sizes to accommodate different screen widths). During the show, you'll hear a tone: hold the X-ray film up to the television and press your head into the screen. Do both profiles just to make sure. Then mail in your film. It's that simple! This week's celebrity test advisor—Chuck Woolery.
