I've never wanted one,have always liked snuggling down under a ton of quilts.But these days when I do that I am still cold for about 20 or minutes.Then there is always that thing in the back of my mind how electricity running across your body can't be too healthy.I know it's dumb but it was a part of the dialogue I heard when I was growing up by my parents. Anyway....what's the worse that could happen? Cancer,right? So who cares at this point.I just bought my first electric blanket,set it on high about 30 minutes before going to bed and then jumped in with my book. Wow...pure Nirvana. There's no going back now.Do you ever use them?
