A St. Louis chemist is one of many people who ask for decaf, and then wonder if it's really decaf. Jack Ladenson says he's getting more sensitive to caffeine. So he wants to test what a restaurant pours him. He's part of a research team that patented a dipstick test. Stick it in your drink and it changes color, depending on the amount of caffeine. He'd like to market it. But, so far, no company is awake to the possibilities. Maybe a cup of coffee would help.
