We have a dear friend in The Villages who tries to test his blood with the INR strips and wastes more of them than ones that are useful. In desperation, because he ran out of strips he set the date and time in the little testing machine backward to accept some expired strips he found from several years before. Seems like a risky tactic but genius on his part. He is almost 90 years old and smart as hell. Have to give him credit for this maneuver even if it is wrong. Coumadin is the medicine he takes.
