Fox News tells us that the post-9/11 decline in air travel delayed the 2001-2002 flu season by two weeks. So if you were one of those who cut back on your air travel after the terrorist attacks, and you were feeling sick arond that time, it probably wasn't the flu. On the other hand, if you live in the NY area and felt sick after avoiding post-9/11 air travel, you were quite possibly suffering from a respiratory illness brought on by the toxic stew of chemicals being spewed into the atmosphere from Ground Zero.

Fantabulous.
