The way to keep people from dying from disease, it struck me suddenly, was to keep them from falling ill. Healthy people don’t die. It sounds like a completely witless remark, but at that time it was a startling idea. Preventative medicine had hardly been born yet and had no promotion in public health work. — Sara Josephine Baker, Fighting For Life, page 83 https://en.wikipedia.org/wiki/Sara_Josephine_Baker
