One more thought on the flu and how it probably has nothing to do with people spending time indoors...

In Phoenix, people spend the summer indoors because of the heat. And, as discussed in the previous post, the people of Bangor Maine spend the winter months inside because of the cold. In the chart below, red indicates months of extreme temperature during which people spend more time indoors.

If the spread of the flu really was caused by people spending more time indoors, then we should see a big flu outbreak in Phoenix in the summer, and a big outbreak in Bangor in the Winter.

Again- this just doesn't happen. As a matter of face, the CDC doesn't even publish maps of the data for June through September because there is so little flu activity.
