A Rare Doctor's Proof

I've been watching a lot of House and Mystery Diagnosis lately and came up with this (weak and not very scientific) proof about doctors.

• Doctors are human
• Doctors are bound by the capacity of humans
• Humans have a limited capacity for memory
• Doctors have a limited capacity for memory
• Being able to make a diagnosis requires memory
• Doctors have a limited capacity for diagnosis
• Doctors can only diagnose what they know
• Doctors are unlikely to make a diagnosis they have not yet encountered either in a textbook, paper, or clinically
  
• Doctors are less likely to encounter rare problems
  
• The rarer the problem, the rarer the doctor
• The rarer the problem, the less likely a correct diagnosis
  

What does this mean? I guess most importantly, don't get born with, or contract, a rare disease or illness. And if you do, you might have a tough time finding a doctor that won't write you off and tell you there's nothing wrong with you because they can't figure it out.


p.s. I had stubbed this up and sat on it for almost a month, only now to finally polish it up a little (and I mean a little) and post it.
