The work of the I’m a Grandma and a New York Yankees fan which means I’m pretty much perfect shirt moreover I love this mechanic can be very complex, so this is not meant to be a comparison. What I understand is that you believe that the work of a doctor can be codified into simple individual skills and relatively clear decision paths. In my experience, even people with no formal training can pick up useful medical reflexes, as evidenced here on Quora.

However, the real skill comes with the part that cannot be put down on paper.
