“Most people are prepared” is a great situation. Regardless, we still see folks in vulnerable situations die when the power goes out in extreme heat or cold. The minority that aren’t or can’t be prepared are the ones that need these guides most.

Heat is typically a problem, you can only take off so many clothes.

Cold typically isn't when at home. That why I have this reaction. You can just put on more and more clothes. There are ways to keep warm. Most deaths from cold are outside, where there are no supplies.
