Heat can be dangerous when you're not accustomed to it. A friend who recently moved from Texas to Cupertino, CA, sent a screenshot of the heat advisory in her new town - it will hit 90^o this week. She being glad that isn't a problem for her to adapt to. Here in North Texas today is forecast to hit 107^o. But for those CA folks not accustomed or prepared for heat, 90 can make people ill or kill some. Same in Seattle (we didn't used to have air conditioning in most of our houses up there.) So New England also - and when it's as humid as it can be up there - ugg. Stay safe, and sleep on a sofa in the lounge if your bedroom is too hot.
