Yes, definitely could be a life save, but you have to be super careful around them b/c they can start fabric and other stuff on fire. I figure that I'll be a little nervous so I'll be a little on the warm side and I have a fur wrap and a
pair of gray uggs to wear outside and when I start to get cold. I will put on a winter coat if it is below 35 that day- I know it will look silly, but getting frostbite will be worse.
