Here’s to, ummm, cholera.

In 1850’s England, physician John Snow decided that authorities were off track when declaring that a deadly outbreak of cholera (also known as Black Death) was due to breathing foul air. Instead, he was able to track the disease to a public well near Broad Street in the Soho district of London. He also pointed out that the well was drawing its water from the much-polluted River Thames. Gross!
