Like "I replace my kits annually and stay on top of the expiration dates. My physicians are awesome about giving me an appropriate quantity so that I can keep them in the car, throughout the house and in my purse. I use the old ones to demonstrate to my family on how to use them should the need arise. While I've never passed out from low sugar, I have gotten close and I have friends who are EMT's/paramedics who have responded to many calls of 'unresponsive' diabetics. By the time they are called it is often too late! If we can educate our friends and family on how to administer insulin and glucagon we are all better off! You know what they say about an 'ounce of prevention'........."
