Audio2design, Like Clint said," A man's got to know his limits." a very important trait for a physician if he does not want to get his a-s sued off and yes, I know some very dumb intelligent people. Physiologically, we all have remarkably similar characteristics and limits within a range. We all have noses and everyone knows what a human nose looks like and will identify it as such even though there can be pretty extreme variations in form, say Taylor Swift as compared to Jimmy Durante. Both of them do exactly the same thing. Noses very predictably smell unless they are diseased. We humans are predictable in many ways, millions of ways.
The major variation in ability to adapt to and function in the environment we have created for ourselves is do to intelligence and training or learning if you will. One a matter of luck and the other parenting. There are exceptions such as personality disorders particularly of the antisocial type of which there are several examples in this forum. They confuse intelligence with arrogance. You are a perfect example of this confusion.
Yes, it was harsh. It was meant to be.
