    Well for me it is incredible. I feel like I have the flu pretty much 25/7 bad yeast digestion issues and I am very sensitive to mold! Well I started the charcoal a few months back and what a difference for me. I could not go to the hallway where mold is without itching and headache instantly and after a few rounds of charcoal no issues at all. I find to it has improved my digestion greatly. Something else I have noticed is for many years I was getting hair testing done which always would show my barium was off the scales high. It would not move or come down at all for over 10 years and I recently did another hair test which showed the barium was over halfway down. I was pleasantly surprised! Look I don't know for sure but I really do see and feel a difference with it. :)

    Not very accurate... My understanding is that the younger dryas begun when a meteorite impacted the Greenland and triggered the beginning of a 1300 years cold period. At the end of the younger dryas the temperatures raised by 10°C I 50-100 years and the sea level rise by more than 100m.

    My son is now colorblind after an overdose that killed him (he was revived, obviously). If you show him any individual thing that is red, yellow, orange, or purple, he sees purple. But if you show him all those things at once, then he can see a difference. It was experimental LSD that someone shot up his nose without his permission. I still don't know who that guy was, but he did it to several people and sent them all to the hospital.

    Hi I enjoy the videos. This one is really fun to use imagination on. Supposing that a nanobot could capture even the most minuscule amount of energy then its just a matter of scaling to high volumes of nanobots to truly cheat and benefit. But my other thinking is nature may have all ready “thought of this” and have some clauses built in. BTW, love the “stop telling me what to do man”.

    What about a treatment where the immune system is completely knocked out like the other two but instead of a bone marrow transplant the patient gets something like marrow inhibitors to stop producing T cells, and gets regular transplants of CRISPR'd T cells with neither CCR5 or CXCR4 receptors. Then after sterilization the patient stops receiving marrow inhibitors or T cells, and their body resumes normal function with the virus completely gone. I don't know how possible this would be, but am curious what you think of it. If it were that easy I'm sure smarter people would have tried that by now. It does leave the patient in a very vulnerable state though, so not good. I think human CRISPR is really the best tool for these kinds of problems, It's already done miracles for less critical issues (and maybe major ones I just don't know of)

    The theory Ive always heard put forward was the chewing aspect. mamalformes and mammals themselves improved the food processing bit at the start of the process with chewing so that dinner was already softened up before it got to the stomach, taking less time and energy off the back end to provide for a more continuous feeding for us, rather than sitting around waiting for our stomachs to clear before going back out on a food search. The reason for that was that as endotherms, we needed to fuel ourselves on a more regular basis in order to maintain that metabolism that allows us to keep a regular body temperature. Chewing and processing our food up front requires more robust jaws, it is said, less smaller bones, so the quadrate and that other small bone...whatever its called, migrated to happily fulfil a happy evolutionary co-incidence and whatnot.

    Natural degradation of the human body since GOD cursed us leading us to have bodies that break down and often have no defences - such as the sailors who took English diseases to the New World and killed all those natives; or two; Syphilis was cooked up by Satan and his gang of fallen angels using tissue and fluid samples collected from Earth. All new deadly diseases such as Ebola and Flu are cooked up by Satan as an attempt to destroy the humans before Jesus returns. Read your Bible, do some thinking and everything comes clear - if you have an IQ higher than most.

    Ouch... I expect better. Sure this is a fluff piece for mainframes. But I expected SciShow to be above spreading misinformation. Where's the fact checking guys? I don't pretend to be a mainframe expert, but I do a lot of work in the cloud. Security: * Cloud can encrypt end to end, so that's not something unique to mainframes. * Yes you're trusting a third-party to secure servers. But it's in their interest for attracting customers to maintain high-standards. I expect most cloud servers are more secure than most corporate IT internal clouds. (AWS publishes all their SOC and NIST compliance reports for example, and I'm sure any other compliance audits they subject themselves too) Dependent on Internet Connection: * If a business can afford a mainframe system, they likely have double or triple redundant internet connections, how would they not have good internet connection? * It's moot anyways because a benefit of the cloud is even if your business goes offline for an outage, the cloud provider is probably still up so business can continue. * Also part of this video was talking about mainframes handling ATM transactions... that requires an internet connection. I don't mean to rant. Yes mainframes have their features and strengths. The ones in this video might even be accurate, but I thought SciShow was above using these kinds of straw-man arguments to favor one side. I expected fact-checking to weed this type of stuff out. I guess, I thought SciShow had higher standards. Very disappointing.

    Tell me, how long will it take to 3d print something heavy, sturdy, resistant, and lasting equal to concrete say to be used as the foundation for a large sky scraper ? Then how long for the building itself, you know all the parts we need to have the properties of concrete that would be otherwise in a 80 floor+ large building? Seriously, concrete isn't going away and carbon is produced in everything the carbon based life on earth does. You want to permanently lock away the carbon in the form of co2? Breed shellfish. Breed them to fill the ocean. Then kill them and do it over and over until all the co2 needed for life on earth has been turned into rock and everything then dies. Start now and maybe you might be done by the time the sun ages and boils away liquid water from the earth.

    I'm old enough to remember that a business had a mainframe and many terminals. The mainframe was the computer. The terminals were "dumb". They had no processing power at all. It was as if you had one computer in your house that had a lot of monitors and keyboards with really long wires attached to it at the same time, and each monitor was showing something different and your keyboard only worked on your monitor. The mainframe would "look" at each keyboard one at a time, process what was typed, and send an "answer" back to the monitor attached to the same keyboard. Technically the keyboard was attached to the monitor, but the monitor and keyboard acted as a single "input and output" device.

And meat especially cooked meat id responsible for our big beautiful complex brains we didn't get from pithicus to homo by foraging for grass, seeds, nuts and twigs! And early on it was discovered that you can't survive by only eating rabbit meat, there's not enough fat in it to produce our energy requirements.

We just started the genetics unit in science (grade 10) and yesterday we were looking at chromosomal abnormalities and things like Down syndrome. As soon as we started talking about differences with sex chromosomes these 3 boys in the back of the room were like "hahaha shemale" and they said stuff like that every couple minutes. The teacher was completely oblivious of course. I tried to tell them that they were being offensive and it completely backfired because now they bully me and spread rumors about me. This is one reason I want to be a teacher, so that there are less people like that. If they understood what half this stuff means maybe they wouldn't act like that.
