1. A Life-Saving Treatment for Diabetes
A diabetes diagnosis used to mean certain death. Before the 1900s, the only treatment was an extreme diet, which slowed the progression but never stopped the decline caused by the disease. In 1897, the average life expectancy of a 10-year-old diagnosed with diabetes was one year. At the age of 30, it was four years. And for someone diagnosed at the age of 50, they were expected to live less than eight years. But in 1921, two doctors at the University of Toronto, Dr. Frederick Banting and Dr. Charles H. Best, began experimenting and made a life-saving discovery—a drug called insulin. While not a cure, the discovery dramatically added years to the lives of millions of people living with the disease. The pair won the Nobel Prize in 1923.
