First off, let me tell you fellas this...MOST so called "Certified PhD" doctors suck to the HIGHEST extent....
Just like in ANY trade...You have bad, semi good, great and BEST..Majority of doctors are HORRIBLE doctors....That's why the best of the best athletes just don't go down the street to Joe Schmo...
And actually, I do BELIEVE most people who are smart can EASILY get a doctorate degree...Believe me, you can't be stupid and know how to build a house from the ground up....Plumbing, electrical, foundation..It never ends...
They learn just as much as anyone else..Just different subjects....
