I Love Being Wrapped Up In My Blanket

I've been reading that heat blankets cause cancer, I don't know how true that is since I've used heat blankets ever since I was in the 4th or 5th grade. But if it causes health risks then, I guess it's adios to this great invention. I hate that I get so cold during the winter months though, putting on a bunch of socks doesn't help warm my feet or legs at all.
