I might be being stupid because I've sweated most of my bodyweight in water but the comments are still a little weird - it said I had to log in, so I went to the blogware.com page and signed in, and I've come back and all I could click was "Reply" to batsgirl's post. And now it wants me to login again below. Anyway just wanted to say the recommendation to keep the windows shut during the day seems really silly. Surely it's best to try to get air flowing through the house as much as possible? With the window shut it would be stifling, you would have no air.
