I recently read Radium Girls, a book about the young women of the early 20th Century who painted the numbers on glow-in-the-dark watch faces. At least they did until their technique of putting the brush in their mouths between each number led to their jaws and teeth rotting out of their heads and early deaths.
The business was really profitable, though. When the GOP talks about job-killing regulations, keep in mind that they are advocating instead for employee-killing regulations.
