Historical pandemics - their past and future; and assessing prediabetes

One of the sessions at the recent World Science Festival was The Pulse of the Pandemic with Michael Osterholm, who spoke about pandemics past, present, and future. He's researched them for most of his career and was one of the first to warn that the current one was going to be bad. Plus recent research on pre-diabetes - which sometimes does not lead to diabetes.
