Health benefits of visiting the cenotes in Mexico Nathan Walz: "So Jack, […] talk about why you chose Mexico for your members retreat." Dr. Jack Kruse: "[…] Most of the reason why we're here is about 65 million years ago there was an asteroid that hit the planet, took out the dinosaurs, and that's when the age of mammals came. And pretty much everybody that's on this call is probably a mammal, so what happened then it set the stage for eukaryotic evolution. And the reason why it's special is about 40 miles of the crust got blown away, so the mantle is really close to the surface, so there's a higher magnetic flux here. Normally on earth the µT is about 0.2 to 0.4 and in most places the earth. It turns out down here it's about 1.2 µT, so it's about 300 to 400% higher magnetic flux, so it's kind of like living on the ultimate Magnetico. "The other big thing here is when the asteroid hit […] it moved all the groundwater from deep in the mantle up to the surface, and it turns out the ground war is heavily deuterium depleted. That's where the cenote system came from, and the cenote system […] is on the rim of the asteroid. Only 13% is still exposed; 87% is actually in the Gulf of Mexico. If you look at a satellite image from Google […] you'll see that the rim of all the cenotes forms a perfect radius of the circle from that original asteroid hit. It turns out all the water from the Yucatan Peninsula comes through the cenote system, and what the governor of Mexico does, there's no lakes here, there's no rivers, there's none of that, it's all from the cenotes. That's from 65 million years of rainwater and groundwater sitting in these kettles inside this crater, so it's highly structured water. Some of the cenotes are open to the sun so they get constant UV year-round. So the water here is special. But Mexico does something really interesting. They actually use reverse osmosis to all the cenote water to further deuterium deplete it and clean it up. So the water here happens to be perfectly great right out the bottle. Now they have mineral water here, they have all different kinds of water, but all the water here including stuff you take a shower in is all cenote water, and it's all reverse osmosis treated. So that's what's good about it. "And obviously we're at the 20th north latitude so you're always in tropical weather. So the weather here, as you guys just know we just passed the winter solstice, so it's the shortest day of the year. Even here at the 20th latitude it's kind of probably better weather than most of you would get at your house on the best day in the summer, so that's what's special about it. And it's not humid; it's actually pretty clear." Dr. Jack Kruse with Nathan Walz @ 03:13–06:46 (posted 2018-01-08)

"They get the vaccine, they did what they're supposed to do, their child is injured." Be thankful if it didn't happen to you. You can't sue the manufacturers. Gaslighting parents with a child seriously injured by a vaccine. Denigrating people who don't vaccinate Aaron Siri, Esq: "Imagine your child has now been injured. And remember, because people always say to me, 'Well, the people who call your firm about vaccine injuries, they're anti-vaxxers.' And I'm like. . ." Lara Logan: "How can they be anti-vaxxers? They vaccinated their child!" Aaron Siri, Esq: "Exactly. The anti-vaxxers don't call (the 'anti-vaxxers,' whatever that means.) They don't call my firm because they don't get the vaccines! These are folks who vaccinated! So, they get the vaccine, they did what they're supposed to do, their child is injured. Before I continue the story, I have one other segue. "People also often say to me, 'Well, if vaccines cause injury I'll know it. I'd know it.' And I'd say, 'Really? Tell me the last three drugs that just came off the market, because drugs come off the market all the time. And tell me what injuries they caused. Oh, you don't know, do you? You know why you don't know? Because it didn't happen to you and be thankful. But that doesn't mean it doesn't happen. OK?' But vaccines won't come off the market because you can't sue the manufacturers, but let's put that aside. "So you have a family, kid is seriously injured by a vaccine, right? Their doctors are gaslighting them and then how are they talked about on the news, especially before covid?" Lara Logan: "Oh, please." Aaron Siri, Esq: "What group can you talk about in America the way they talk about people who don't vaccinate? Can you imagine? Replace what I'm about to say with any minority, any religious, any ethnic group. You ready for it? 'Throw them out of school.' 'Throw them out of their jobs.' 'They're selfish.'" Lara Logan: "'Don't treat them at the ER.'" Aaron Siri, Esq: "'Don't treat them.' 'Let them die.' 'They deserve it.' Who can you talk to about like that?"

Should a 20-year old consume deuterium-depleted water? How about a 53-year old? Nathan Walz: "Lynn wants to know if she should give her 20 year old son deuterium-depleted water, or would somebody his age need deuterium for growth and development?" Dr. Jack Kruse: "Yeah, I'm gonna tell you that I think that deuterium-depleted water for the first couple of decades, unless somebody has a significant mitochondrial disease, it's not needed. Deuterium-depleted water is best when heteroplasmy rate is higher. I wouldn't assume a 20-year old would have that, unless the kid was born would say a childhood cancer, or an autoimmune condition, or some kind of tumor. That would be the only time I would do that. "It's a good thing to do; don't get me wrong. I still think it's not a bad way to go. But the deuterium-depleted water pathway is a backup pathway. You're designed to make it mostly in your mitochondria. But you can offset a bad mitochondrial matrix by utilizing the oxidative branch of the pentose phosphate pathway. That's actually how drinking water can affect that. It also then has a spillover effect to another pathway, and that's called the NADPH pool. That pool is designed to really take care of RNA and DNA. And usually in young people that's not a big deal. There's another backup pathway that I've written about on my Patreon blogs. […] It's called the serine glycine inner conversion, and the way to use that is to use animal fats or plant fats to access that, and that's another way for you to help fix your matrix. "But again, that's also something I don't think a 20-year old really needs to do. Really, the key stuff somebody's 20 needs to do is the stuff that we talked about on the regular on the regular site, like the leptin prescription, cold thermogenesis, eating a seasonal diet, trying to mind your EMFs, definitely blocking blue light at night. Because if you don't do those things that's actually what allows the deuterium to go into your matrix, and then that leads to heteroplasmy or diseases, so that when you are me and Rich's age, you got to worry about it. "I'm 53, Rich is 65. For us, deuterium-depleted water is a good thing. Why? Because I'm in my sixth decade, Rich is in his seventh, and we know from Doug Wallace's work that every decade we live our heteroplasmy by chance alone goes up 10%. So him and I are closer to our ends so we need to do more, and that's why him going to the cenotes, and me down here drinking a lot of deuterium-depleted water from the cenotes, that's part of the reason I come here so many times. This year alone, this is my eighth time in 2017, and I'm here for a whole week and I'll be here for another week. This place is, when you said, 'Is it the Fountain of Youth?' You say it in a joking fashion, but to be quite honest with you, when you have a high heteroplasmy rate, this place is the shit. That's all I can tell you."

The human brain's preferential fuel is ketones, not glucose. The lower limit of carbohydrates in the human diet is zero. There is no such thing as an essential carbohydrate. Why chubby babies Anthony Chaffee, MD: "This is something people talk about, that glucose is the brain's primary energy source. What do you say about that?" Benjamin Bikman, PhD: Yeah. […] I just […] presented at […] the meeting of the American Association of Biological Anthropologists. […] I felt compelled to inform the person reaching out to me, […] 'Look, I'm a nutrient biochemist, mitochondrial physiologist. What do I have to say?' And he had said, 'I'm familiar with your work on brain energy use. I am putting together a session about the changes in […] our ancestor diets over these periods of evolution, and I want you to talk about the brain acting as a hybrid.' […] "I […] shared with them a quote by the National Academy of Sciences in the US stating that the lower limit of carbohydrates in the human diet is zero. In other words, there is no such thing as an essential carbohydrate, and the idea that the human brain evolved because our ancestors ate a lot of carbs, that's utterly ridiculous. […] It's because they mistake dietary carbohydrates with blood glucose. What does appear to be the case is that the brain has some demand for some glucose. That appears to be accurate, although the lower limit is unknown. Early work by a fasting physiologist named George Cahill, he was putting people's glucose down to like 20 mg/dL, which most people would say you're unconscious, you're in a coma, and you're going to die. And these people, because they've been long-term fast adapted, which I would say ketone adapted, there appeared to be no deficit to cognition, and that's a pretty bloody low level of glucose. "But nevertheless, let's kind of grant that side of it, that the brain has some requirement for some glucose. Well it is a minimal requirement, because if you take a body that has five millimolar (mM) glucose, then you start increasing the ketones to one or two or even 3 mM, which is still less than the 5 mM of glucose, so there's still less of the ketone in the blood than there is the glucose, by then the brain has already dramatically shifted its energy use. And even though the ketone may be less than half of what the glucose is in the blood, it's now providing twice as much of energy to the brain as the glucose is. So if the brain has any preferential fuel, it is absolutely for the ketone. […] "You can take a newborn baby, and the baby can breastfeed or bottle feed, and then within an hour the baby is in a deeper state of ketosis than an adult would be after fasting for a full day. That baby will be at 2 mM ketones in an hour. And an adult, for me, if I want to get to 2 mM, I gotta fast for like 36 hours to get to that point. So if there's any natural state, […] it is clearly that a natural state is a state of ketosis. […] "We are such totally unique creatures, where we are the only land-based mammals born obese, and the only animal who has a brain that is larger than the birth canal, much to a mother's chagrin. But that means we have these very big hungry brains, and all of this chubby, adorable baby fat that is just producing ketones like gangbusters to fuel the brain growth. And if you have a baby that is born premature and lacks sufficient adipose tissue, it is much more likely that they're going to develop neurological disorders, all the more reason to chubby up that baby as quickly as you can."

Humans suffer neurological disorders without earth's Schumann field. Schumann simulators for astronauts "_Schumann radiation_. This spatially coherent, non-ionizing electromagnetic radiation represents the transverse electromagnetic normal modes of the Earth's ionosphere cavity whose source is the totality of global lightning discharges. […] "Isolation from the Schumann field (and also from the Earth's magnetic field) during space travel (beyond the ionosphere) correlates with the onset of certain neurological disorders in astronauts. To counteract this, Schumann simulators are now fitted into spacecraft."

The myth that the sun is toxic. The medical curriculum is subsidized by big pharma Meredith: "What would you say is the biggest myth that people have about going out in the sun?" Dr. Jack Kruse: "That the sun is toxic. That is absolute utter nonsense. If it was, every wild animal and all these beautiful trees around us would have every rip roaring disease, and it turns out we're the only animal on this planet that has chronic disease epidemics. And what do we do? We come out of our mama, we wear clothes, we wear sunglasses, we have sunscreen. […] It's almost ludicrous. If you took your three children to one of the farms that are up here, and you saw a baby horse or a baby pig being born, would they come out with Abercrombie & Fitch on it? […] Is there any animal that does what humans do? Maybe we need to start asking those questions right then and there. Maybe we need to start questioning anything. […] "I always tell people it's the mark of an educated mind to take something you fundamentally do not believe, so any physician watching this who doesn't believe that the sun is helpful for health, you need to hold that concept in your mind, go examine it, go look at all the papers that are out there. You might be shocked at what you find. You may find that what you learned at Harvard, Yale, Cornell, UCSF, UC San Diego, any place you want to go. All of those places, the medical curriculum is subsidized by big pharma. Shocker." Dr. Jack Kruse with Meredith @ 27:20–28:22 & 30:22–31:02 (posted 2020-11-13)

Information is energy. Light has information in it. When you're in the wrong light, you delete melatonin, you delete your life force. "What's the defect in the environment that led to this disease state?" Dr. Jack Kruse: "And it turns out with information theory, what does it say? When information is lost from light, mass has to be expended. […] "Information is energy. That's the leap. And it turns out that light has information in it. Well if you're a doctor, don't you think you want to know what kind of information your patients are getting? Do you think the information in an indoor blue-lit world is maybe different than the one that comes from the sun when you're outside in the morning? "And do you think that may have bigger implications then maybe you currently think now and just because we live in indoor existence and 99.8% of the light that humans live under today is manufactured, that should be a stunning realization too. You should say, 'Well, if we're living under this light that we created from Tesla and Edison, how is this ruining information signaling?' Like are we making all the zeros and ones that we're supposed to? Is disease maybe tied to what Jack just said, when information is lost in a system mass is lost. "Well last time I checked melatonin is made out of mass. When melatonin is lost, you lose the two change programs in mitochondria. You can't change them. So guess what? Now I just explained to you that a loss of information of your light can actually create losses of things with mass [snaps fingers] overnight. Like it doesn't have to develop; there's no prodrome. [snaps fingers] It [snaps fingers] happens [snaps fingers] like that. Why? Because how does light work? Photons experience no time, and you keep forgetting that. […] "I tried to give you that clue about the light bulbs in your house. I want you to understand that when you change the light bulbs in your house compared to that sun behind me, that ultimately it's going to lead to a deletion of mass and different proteins in your body. It turns out that those proteins might be some of the most important proteins you have. Like melatonin, everybody thinks about sleep. It's not, it's really not. Melatonin controls actually how good your engines are in your body, which are your mitochondria, through those two change programs you talked about. […] When you're in the wrong light, you delete melatonin from the system. That means you deleted your life force. OK? […] "Is anybody really asking the fundamental question? Like, 'What information in my environment is being lost that's causing a problem in my life?' No, because the patient doesn't know to ask that question when they show up in your office. It's your job as a clinician to say, 'What makes this person unique? What about them is causing them to lose information from the waveforms in their environment?' Instead of looking at the defect in them, […] maybe the way we need to think about this, 'What's the defect in the environment that led to this disease state?' Then maybe you'll get a different answer than you've gotten from doctors for 10, 15, 20 years."

Practicing cold thermogenesis at age 14: "I would always go out with a wet head. […] I'd ride to school on the subway, in between the subway cars, and my hair would freeze." Why cold thermogenesis is useful for many diseases Dr. Jack Kruse: "I remember distinctly, waking up in New York City, going to high school. I would always go out with a wet head. At the time I used to have curly hair like Robert Plant from Led Zeppelin, and it used to go down the back of my head. I would go out with it soaking wet, it would make my coat wet. I'd ride to school on the subway, in between the subway cars, and my hair would freeze. Every day my mom was convinced I was going to have pneumonia, I was going to die. Turned out when I was that age, I was the only one in the house that never got sick, even living in New York City, traveling in a subway. That's the effect of cooling on your head. That's something called cold thermogenesis. "Well, let's fast forward now 30 years. I'm a neurosurgeon. What do I do when someone gets their head bashed in? I cool their head to improve their function. Why? Because it actually makes mitochondria a more thermally efficient heat engine. How about that? So guess what? The same principle that I didn't even know I was doing at 14 years old, now at 55, people are paying me money for it. "And when I teach people to use it for different diseases now, their primary care doctor will say, 'Oh well, you know, we're not talking about your head kicked in. We're talking about you having diabetes, or we're talking about you having obesity. It won't work for that.' Well, it won't? Tell me why it won't? And they can't. It's the height of ignorance and arrogance for someone not to examine the science behind something then go out and tell the public, 'Oh, this won't work.' […] It's an epidemic in medicine right now. Huge epidemic. "And I always tell people, it's the mark of an educated mind to take something you fundamentally do not believe, […] you need to hold that concept in your mind, go examine it, go look at all the papers that are out there.
