Quote of the Day
"The lesson to armchair epidemiologists: picking winners in the middle of a fight is a mistake. Recall how poorly last month’s claims of victory panned out before rushing to declare new winners this month. Recognise that the virus has a long-term survival plan of its own."
(Ruchir Sharma)
