That a bit of hyperbole, people don't take antibiotics for minor scrapes - soap and water is the prescription. quite often when the minor scrape is life threatening, its something like MRSA. which leads me to think of the stories of people in the past dying of minor scrapes: maybe its been around for longer than we think.
after all of the scare tactics, much of the drug resistance where it matters has been appropriate use. TB, gonorrhea, etc. These diseases didn't become drug resistant because people were taking antibiotics for the flu or use in agriculture.
