Have I told you how swelteringly hot it's been here recently? How we cope with it is by closing all the shutters during the day time to keep the house cool and opening them at night to let the colder night air pour in.
Also, I've started carrying a fan around in my handbag and, the more I use it, the more it makes sense. Think about it for a moment. Here's a device that folds up to nothing, is as "green" as it's possible to be (the only energy you're using is your own) and really, really works. And then there's the whole language of the fan.
Here are the three fans I currently own. Two I use, the first one's simply to look at.
