   • 1936, Dale Carnegie, “Part 1, Chapter 2. THE BIG SECRET OF DEALING WITH PEOPLE”, in How to Win Friends and Influence People, page 41:

     What is the cause of insanity? Nobody can answer such a sweeping question as that, but we know that certain diseases, such as syphilis, break down and destroy the brain cells and result in insanity. In fact, about one-half of all mental diseases can be attributed to such physical causes as brain lesions, alcohol, toxins, and injuries. But the other half—and this is the appalling part of the story—the other half of the people who go insane apparently have nothing organically wrong with their brain cells. In post-mortem examinations, when their brain tissues are studied under the highest-powered microscopes, they are found to be apparently just as healthy as yours and mine. Why do these people go insane?

   • 1980 March 7, Billy Joel, “You May Be Right”, in Glass Houses‎^[1]:

     But I made it home alive
     So you said that only proves that I'm insane

   • 2018 August 8, Bill Graveland, “'I'll get better': Paralyzed Humboldt Broncos player working to improve at sledge hockey”, in CBC‎^[2]:
