Smart dentists have their dentists.
   Smart doctors have their doctors.
   Smart Lawyers will have their lawyers.
   That's not to say there aren't some lawyers who have themselves
   as clients because it's likely they do. But they really
   shouldn't. But:
   If I were a lawyer, I wouldn't want a lawyer as a client.
   If I were a doctor, I wouldn't want a doctor as my patient.
   If I were a dentist, I wouldn't want a dentist as my patient.
   Interestingly, Insurance companies have their own Insurance
   companies. I believe it's called Reinsurance Companies. They're
   larger than the planet, that is, if you believe money has an
   equivalent in physical size. researched 'cause I was curious
   myself:
   [1]https://en.wikipedia.org/wiki/Reinsurance
   Lloyd's of London was the first Reinsurance company. That's an
   example. Supreme Court Justice : All other Judges in the USA ::
   Lloyd's of London : Regular Insurance Companies at least in my
   mind. I don't know much about the subject otherwise tongue
