I didn’t use the chinese medicine system to build the neurotyping approach. I used neurotransmitter levels and personality profiles. It’s up to you if you prefer to go with a system based on tradition and beliefs or science
But of course, using chinese medicine make it sound secretive. And Charles being from the martial arts milieu originally, chinese concepts are kind of his thing (he also teaches the use of pressure points on the acupuncture points to improve strength and mobility). So he went all out on that. Plus, using such a system allows you to answer questions without having to give a complete scientific answer.
Yin and Yang to me likely refers to excitory neurotransmitters (dopamine, adrenaline) and inhibitory neurotransmitters (GABA and serotonin) with Acetylcholine being in between because it can have an impact on both functions. Which is likely why Charles think wood is acetylcholine. But really what you need to understand each type is to know:
- How each neurotransmitter affect behavior and body function
- How to use someone’s personality traits to evaluate neurotransmitter function
- From their neurotransmitter function efficiency you can understand WHY something work and why something might be a problem.
Ask me ANY question (you have already asked a lot, and others too) and I can ALWAYS give you a profound, complete and scientific explanation behind WHY it happens. I don’t give short answers that don’t really give you what you need to understand what is going on.
I love Charles, he is my mentor and the person who had the most impact on my life. But for me if someone aks the question: “Why does a fire (or 1A) type prefers heavy lifting and can recover fast for neural workouts and prefer to take long rest intervals?”
What answer would you prefer/thrust more: “Because he has more yin”
“He prefers to lift heavier because heavy lifting leads to a higher neurological activation due to to an higher dopamine release and since Type 1A is dopamine sensitive, he has the greatest response to dopamine which is the pleasure neurotransmitter, so heavy lifting gives him more satisfaction. He can recover well from heavy lifting because of his high level of serotonin which can quickly inhibit/calm the nervous system after the intense effort. As a result the CNS doesn’t stay over-activated for long which decrease the energy drain on the nervous system and also minimize cortisol production (doesn’t stay in sympathetic mode for long). Finally, they instinctively prefer to train at a slower pace to minimize adrenaline release. Since adrenaline is produced from dopamine, and because Type 1A have LOW dopamine (due to their high sensitivity to it) if they produce too much adrenaline (which happens when you train faster) they risk depleting their dopamine level which can make them crash.”
I really don’t want the conversation to go this way. Charles has his system based on his beliefs I have my system based on my beliefs. Look at the information provided by both, or even talk to people who have been to both classes and make your opinion from the information.
