Dear Heloise: I am a senior citizen living by myself in Northern Indiana. Right now, we are in the middle of a blizzard. As a safety precaution, if I absolutely need to go outside on these cold days, I always make sure I have a house key in my coat pocket. One never knows when a lock could accidentally get turned on the way out the door. The results could be deadly. Stay safe.— Michael Noll, via email
