welcome to the forum
I do watch both of those gentleman, on YouTube, on a regular basis.
And now that you have reminded me of Joey Carbstrong, it takes me to the question you asked about being able to change personalities with eating a plant-based diet and Joey is a great example of this. His life, previous to being vegan, was considerably different from his life now and I think he would be one of the first to admit that being vegan has changed him, and for the better.
