All you had to do was ask for video of their work....and you would be given the keys to the smart kingdom.
But you choose to remain stupid.
Make sure you understand this....
YOU CHOOSE....to remain stupid....by not demanding the information needed to answer your questions.
It's like taboo to ask someone to prove they have knowledge.
Here is a PERFECT example of the ignorance....
The angle in the rear arm.....IS A SURFACE FACT. It has little to nothing to do with the under the hood truth. Keeping a pinch in the bicep happens....it's a good thing.....but you can keep a pinch in the bicep and still be TOTALLY WRONG. He has NO IDEA what the truth is.
The rear arm is all he can see....because he's never felt the truth.
And you're afraid to ask him for some truth proof.
Yet.....you discuss hitting with him.
Ignorance might be the most abundant commodity.
