I coudn't possibly have sex with the window open as my #$%^%$#@$ neighbor is almost always puttering in his driveway - which my window opens to!!!I have worked in buiildings where the air quality seemed to make me ill. Over-air-conditioned in the summer and such. I don't think the windows even COULD open, if I recall. Just a glass space in the wall. Fortunately now I work mostly outdoors.
Has anyone tried one of those negative ion machines? Whad'ja think?
