i read the latest national geographic and the answer seems to be because it faltered because of the buildup of fluid in it's lungs... fell because it was bleeding to death from a internal hemhorage (sic)...and finally was run over by a mack truck symbolizing the general lack of concern on the part of those who stand to lose dollars and nuyenin the cleanup process.

i especially liked the coy manner in which the article didn't make reference to any possible aid from human scientists this flu strain may have received...when ya know damn well they are trying to recruit biological disaster scenarios more desperately thanNotre Dame is trying to schmooze football players
