Pandemics are the fattest tales. And fat tales means that these things can really go out of control. We haven't had many pandemics in history, but we've had ou very little ones. They represent an existential risk, and we knew that. So you have to stop some things in the egg when it's cheap to do so. When ibola started, the people were not reacting to it properly. Try to guess alsars going to be either nuclear war or pandemic. More likely to be a pandemic, especially fatestales.
