I know Dave and can definitely  say that he's not a moron.
You're right, Dave is a smart man and definitely NOT a moron. 
He dropped out of a med school midway by his choice and got a BS (with honors) in biochemistry.
 At the 2008 Arnold expo, I  asked Dave's buddy, John Romano, if Palumbo ever had regrets for not getting his MD.
JR gave me a rambling, reply about how he and Dave were doing more without the constraints of 
"established credentials". 
Ok, that's fine. 
BUT you need to be a real doc to operate and prescribe meds. 
You need to be real lawyer to represent others in court, etc
In 2000, I  asked , if he was trying to change his look , so he could win and go pro.
Dave smiled, looked me in the eye and said ; " I'd rather not go pro IF I have to sacrifice muscle or look less freaky ."
he claimed , he  was doing better "as is" and didn't really need a pro card.
Dave Palumbo was/is a straight shooter and lives life on his terms. 
BUT his refusal to comply with basic, established requirements, came with a  cost.
As an " outsider" you limit what you can do for people in normal, daily life.
Many love the renegade spirit but sometimes , it's just not practical.
Most of us want our car fixed by a certified mechanic . 
LOL, unless you're at home, you need to be a licensed beautician  to cut hair  .
