 I got contacted by the State Department because I published a paper where I did this statistical analysis which showed that the subway line next to the Wuhan Institute of Virology was the same line that went to the International Airport. And you can go all over the world in 12 hours before you have any symptoms from that airport. And they called my secretary and they said, hey, can you come in and help us? Because this is really interesting information you have and no one else has done this before.
