Ancient Nubians Drank Antibiotic-Laced Beer

A group of people who lived nearly 2,000 years ago in Sudanese Nubia took doses of tetracycline -- through their beer.
Human use of antibiotics began not 80 years ago, but nearly 2,000 years ago along the banks of the Nile River.
Those ancient people got tetracycline out of fermented grain that they used to brew beer.
Everyone drank the antibiotic-laced beer often, starting as early as age two.
