Put your car remote by your bedside. If you hear someone trying to get in your home, press the panic button on your car alarm. It should scare them off. It would also be useful for something such as a heart attack. If you carry it on an icy morning when you go out to get the newspaper and fall down, you can set it off for help. Doris said when you press it in a parking lot looking for your car and nothing happens, hold it under your chin and press again. It will reach a broader area.—SNUG Oklahoma
