My 46-year-old DH has recently been complaining about a pain in his knee, and shared this concern with his buddy at work. His buddy recommended to take some Glucosamine.... ..so tonight DH is telling me about this miracle drug, and the testimonial of his work buddy....all the while I am walking to a kitchen cabinet... ...where I toss him the bottle and inform him that he has been giving to our elderly dog for years!!!!! (She's in better shape than he is!!) --he called his buddy back and says, "Man, she's put me on dog meds!"
