    If the numbers infected double every five days , how long before the whole world is with the virus

    Let's presume the number today is 20,000 and the world population is 8 thousand million

    A date

    The minute you hear the phrase: 'Exponential increase.'

    Run like F***. (Not 'away,' but toward the pub. You might make it that far …. ) :buddy:

    Unless the phrase is used by a politician … in which case … take all the time you need to get to the pub … bearing in mind said politician will probably have jacked up the prices by the time you get there.

    :bum:
