Well, summer will be officially over on or around 20100921, the autumnal equinox. This is the day when the nights begin to grow longer than the days, just like the vernal equinox, when the nights grow shorter than the days. It all has to do with the unique orbit of our wonderful spaceship earth as it orbits the sun. Perhaps near that date I cam elaborate.
This time, however, we shall discuss the beginning of the cold and flu season, and how to deal with it. I have only two rules, and they are important. Observe them and you will have fewer of them, I suspect.
