Hands on experience is different than Education, which is different than critical thinking.
Some of the dumbest people I know are Doctors, 2 in my immediate family (neither one can change a flat tire, or tie their shoelaces properly).
And by the way, your education never ends... and an MD from 1984 doesn’t mean squat as it pertains to the subject that is being talked about.
Appeal to perceived authority does not transcend hands on/applied understanding.
