@@ZeroToFinals I know it's standard, but I don't think CRP should be used as the only indicator for inflammation. I have always had normal CRP, yet had bladder inflammation, joint pain, muscle pain, and sometimes bone pain for a couple of decades. It looks like I have a few type 4 sensitivities. One of which is nickel. It's in everything 😞. Specially plant based foods you would normally consider to be healthy Chocolate Nuts, Beans, Legumes, Oats Green leafy vegetables

It makes the immunity system way much more clear than I have ever known. Teachers usually just use PowerPoint and giving us hard terms to memorize and then ask students to visualize the process itself, which is mind-blowing and not an effective way of learning. Really thanks for your video, so i can joint all the clues together and have a good understanding of the immunity response. Good job! 👍

I was diagnosed with a rare autoimmune disorder (TTP) last year. I've read a lot about it and understand most things about the disorder, but now I've started learning more about the immune system and trying to understand autoimmune issues better. This was a FANTASTIC starting points. My studies and occupation have nothing to do with medicine but this was still very easy to follow and gave me all the clues I needed to go down the rabbit hole. Thank you!
