"I used to believe that blue light was the big issue, but I think I would put polarized light on top. That's all the light that's man-made. I'd put blue light second, because there are some versions of blue light that are not damaging. […] Fire was the first non-native EMF light." — Dr. Jack Kruse --- Andreas David Christou: "Would you say that artificial blue light and non-native EMFs contributes to brain damage?" Dr. Jack Kruse: "It's the cause of brain damage, most of it. And I think it's the number one cause of all diseases. I think if you really wanted me to break it down, I used to believe that blue light was the big issue, but I think I would put polarized light on top. That's all the light that's man-made. I'd put blue light second, because there are some versions of blue light that are not damaging. […] "Fire was the first non-native EMF light. Why? People don't realize that fire is partially polarized, and we even have evolutionary proof that that light is enough to change us. Why? That's how Neanderthalss lost 125 grams of brain and we took over for them. So their brain shrunk and we showed up. But the real true part of this story that links to this Neanderthal story that people don't like to hear, people think all these new diseases, they call them Neolithic diseases, that's bullshit too. Why? Because all you have to do is go to Egypt and look at the King Tut exhibit and you'll see the mummies in the ground who lived inside with the fire versus the Nubians that were buried on the side of the Sphinx. The Nubians were perfect humans, perfect skulls, perfect dentition, thick outer and inner table of their bones. These were the guys that built the pyramid and the Sphinx. They were they were as healthy as healthy could be. We can tell from their fossils. And yet, when we x-ray King Tut and all the pharaohs, they have all the diseases that we have. "Remember, there was no power grid then. So, what does that tell you? How really important light is. And that light, fire light, is only partially polarized. So why did I tell you that I put polarized light above that? Because probably in the last 10 years, I realized that I was doing my tribe a disservice. "Even fire light from candles disrupts melatonin. It's not very much, but it does it. And if it does it, that means it can start this process of unraveling the evolution of what happened on the inner mitochondrial membrane. And I think people need to know that. "It's the same reason why I don't do affiliate marketing for red light guys. Why? Yeah, it's good, it's better than the LED lights. But remember, most of the red lights you have, they're all polarized. So, are you really doing yourself a favor? The answer is no. So, why do you always see on Twitter when people ask me what's the best red light? I always put Sun is TINA. What does TINA stand for? There Is No Alternative."
