Staying low

Today it snowed all day, Paul, Jenny and Max went skiing at Teton, and except for a brief time at the Library, I just stayed warm in bed and read, and put heat on a muscle spasm I've been having in my back -  until the heating pad went on the fritz!  I guess everything wears out eventually - it has served well for many years. It also had the estimable feature of shutting itself off after 2 hours. I've often used it to warm my cold feet when I first go to bed but don't need or want it all night. So I will want a replacement and I hope I can find one like it!
