[@JHaven-lg7lj]

I wish we could get to the point where we’re allowed to listen to our bodies telling us to slow down and rest when we’re fighting off and infection, rather than pushing through because we must be productive at all costs.

[@ReplyGPT]

You make a very valid point. In many societies, there is a culture of valuing productivity and pushing through illness or discomfort to meet obligations and responsibilities. However, listening to our bodies and taking the time to rest and recover when we are sick is important for our overall health and well-being. When we are fighting off an infection, our immune system is working hard to combat the invading pathogen. This can take a toll on our body, resulting in fatigue, pain, and other symptoms. Pushing through these symptoms and continuing to go to work or school can prolong the illness and make it more difficult to recover. Taking the time to rest and care for ourselves when we are sick can help us recover more quickly and prevent the spread of illness to others. It is important to prioritize our health and well-being, even if it means taking a break from our usual responsibilities for a short time. While it may be difficult to change societal attitudes towards productivity and illness, we can start by setting boundaries for ourselves and prioritizing our health. This can involve communicating our needs to others, taking sick days when necessary, and practicing self-care to promote healing and recovery.

[@infested4494]

Also, when you sleep, the body makes more cells that identifies what's a pathogen and what's not. That's part of the reason why you die if you don't sleep for a few days, because your body won't be fighting the pathogens in your body if no cell told the immune system that certain micro-organisms are hostile to the body.

I hope you guys do a video of the Immune system going wrong. As someone with Type 1 Diabetes and Vitiligo, both caused by a hyper-active immune system response, it would be great to see you guys show the light on this subject

[@Fleetstreetbestone]

I’ve been watching these guys for a while now but I find the fact that they didn’t even mention having a healthy lifestyle which has been proven to immensely boost your immune system and health in general, quite disappointing. Eating unprocessed, natural, healthy foods while getting regular excessive can decrease your chances of dying to illnesses drastically, I mean just by not being obese you are 40% less likely to contract covid when exposed to it. The fact that 41.9% of adults in America are obese and they didn’t even clarify this in their video, only focusing on vaccines despite the covid vaccines being very controversial due to the shady nature of Phzier and the censorship of information on lobbying ect. and also 16.0% of female participants reporting LTAEs which were mainly fatigue, menstrual disturbances, myalgia, arthralgia, dizziness, and headaches, is just shocking and seems misinformative to be putting this out.

While the book has some incredible insights and cool bits of information about the way the immune system is set up, I personally hated the writing style. It takes several detours and makes several unnecessary analogies to get to every single, fairly straightforward point. It's like it was written for primary school students, not all ages. It's still a great way to support the channel and I don't regret buying it, but unfortunately, it's pretty bad both as a pastime and as a source of information.

[@Leyrann]

Can confirm this! Outside of when I was a small kid, I've had severe diarrhoea (as in, several days of going to the toilet every 30 minutes) twice in my life. And both of those times were within three years after I got measles. (and I didn't even get them all that severely because I'd received my first measles vaccination a week or two before I was infected - and for those who are no doubt going to wonder, there were medical reasons why I didn't receive the measles vaccination as a kid, and the decision predated that fraud paper anyway)

I have found that antibiotics help by increasing my immune system, or helping it along. In a way the pandemic was a bit of godsend. For 2 years I never got sick because I almost never went outside except for the supermarket. This last year I have gotten sick a couple of times, but I've had all my booster for Covid and the flu shot. The most I was sick was 2 days which I cannot remember ever happening. I wish, though, that I didn't have to live in a bubble. I wish people would take common sense precautions. If you're sick, stay home!

I'm living this now. I got pneumonia just over a year ago and was hospitalised. By the time they diagnosed it and got antibiotics in me, it had spread across half of my left lung. Before that I was relatively healthy, but ever since - even over a year later - I now struggle to breathe sometimes and any little cold makes it hard to get enough oxygen. I'm only in my late 20s but I'll probably have weakened lungs for the rest of my life now, all because I picked up a bug from the electrician who came to repair the light switch.

All resulted in hospitalizations for 5 days to 1 month. My pneumonia’s have been nasty lately and all of them required IV antibiotics. I also have autoimmune issues so I’m immunocompramised and also autoimmune. I think I pissed someone off in my past life. So many hospitalizations and multiple bronchs as well. My last pneumonia I had double septic pneumonia. A week in the hospital with a bronch. One week isn’t bad though. A month had me so depressed and I missed 3 Christmas holidays out of 6 due to being in the hospital. I feel your pain. I hope you are doing better now.

I doubt this video is one of those though, as the main topics presented are based on solid facts rather than subjective personal preference.

The fact that 41.9% of adults in America are obese and they didn’t even clarify this in their video, only focusing on vaccines despite the covid vaccines being very controversial due to the shady nature of Phzier and the censorship of information on lobbying ect. and also 16.0% of female participants reporting LTAEs which were mainly fatigue, menstrual disturbances, myalgia, arthralgia, dizziness, and headaches, is just shocking and seems misinformative to be putting this out.

I got to experience a virus that made me weaker when I was 20. This is a long story that took/takes place over 6 years so far. I got sick while on vacation in Florida and I did something you should never do. I took medicine while drinking some beers(also yes it was underage drinking I know). Sickness seams to go away mostly but then on the drive back home I was getting really dizzy in the car but that got better. Then when I went back to work I was having trouble standing for more than 5 min before getting dizzy. I went to the doctor the next day because it had then been 3 days of dizziness they did the normal thing and weighed me and all that. I weighed in at 149 lbs which was low from my normal, but still low for a 5'11" guy, 160 at the time. They gave me a shot, told me to go to the ER if it got worse, and sent me on my way. 3 days later I got a friend to bring me to the ER because I was getting really dizzy even when sitting down and laying down made it worse, I got the first of many migraines, and my hands had started to shake a little bit. Got there and they weighed me in at 141 lbs. Which I didn't believe and I showed them the paper work from the doctor of the tests they did that I brought along just in case it would help. That plus the dizziness got me scheduled for a CT scan. Now the radiologist aren't supposed to tell you anything really and she didn't but the look on her face when she saw the scan and how she just left the room was quite worrying. I get put into a room so I can get an MRI in the morning after a second CT scan. All the doctor says and shows me is that there is a weird spot in my brain around the base of the skull about the size of a thumb. That night I get weighed again and weigh in at 138 lbs. That made the nurse rush out and get the doctor to show him. They then told me they were going to weigh me a couple more times throughout the next day. Got weighed first thing in the morning and weighed in at 131 lbs. Got an MRI and got brought back to my room. Learned I couldn't walk without holding onto something anymore and my hands shook enough that I couldn't hold the fork for lunch. The migraines blurred my vision more than it already is(I wear glasses). They felt like someone was running knives over my head branching from the back of my head forward. Doctor came in and weighed me again after a second MRI. I was down to 128 lbs. They also got a neurologist to come in he then took all the data to a team 3 neurologists(that turned to 9 later). He told me not to worry because from what he could see it was just some minor inflammation with no signs of getting worse over the couple of scans they did. Blood work was done as well and that showed that there was no virus present anymore so we never found out what I got exactly. The next day I get weighed in the morning again and weighed in at 124 lbs. Did another MRI and then the neurologist came in with what was basically a drawn and printed out powerpoint presentation and he got one of the other neurologists on a video call. He went through explaining a lot of what they found and how the only case they found similar to mine was some lady in 1993. He told me what happened to me was about a 1 in 300million chance and in part I was lucky because it could've been much worse. The virus had gotten past the blood brain barrier which was probably weakened by the alcohol and medicine combo. That caused a slight over reaction in my immune system which led it to keep fighting even after the virus was gone. He told be the inflammation would go down in a couple of weeks or months but the nerves where permanently damaged. Good thing was that I was young so my brain would eventually learn to use other pathways to do the same jobs. I asked him how long he thought that would take and he told me that if I agreed to do some physical therapy then it would probably take about 8 years to "heal". If I was younger the damage done probably wouldn't have affected me for that long but because my brain was almost done developing it needed more time. If I was older there would have probably been no hope for going back to normal. When I got weighed in the afternoon I was still 124 lbs. I had lost basically all my fat and about 40% of my muscle mass. The doctor then told me that if I had lost even 1 more pound he was going to put me in the ICU but then he gave me the option to go home as long as I would come back if I felt anything getting worse. I also had to come in for tests and MRIs the next week and every 2 weeks after that for a couple of months. They gave me a couple of medications and even wrote on a note attached to the prescriptions that i should use protein powder to help gain my weight back. I then started 6 months of physical therapy. The dizziness became persistent while I was in the hospital and got worse over time. The physical therapy made it better but for about a year straight I was always dizzy. Couldn't even watch TV without feeling like I needed to puke. Looking over at something to quickly made it feel like I did a flip. I couldn't write easily but I kept practicing and part of that was the muscles in my hands being so weak that holding things became painful after a little while. After a year I was doing a lot better. The migraines became very rare and I could walk around for a couple of hours before feeling to light headed. Now 6.5 years later I'm basically back to normal. Sometimes my sense of balance just "turns off" so I can't feel if I'm standing upright or not. It is usually followed by a sense of falling when it comes back. My hand shaking and all that was getting rarer but recently came back for another extended round of annoyance. So every once in while I drop things and typing this out I would hit the same letter like 3 extra times (good thing for auto-correct). At the rate it's going idk if I will ever get back to normal but it is a lot better than what it was. Though I don't have that weight problem anymore as I am now around 200 lbs and am physically stronger than I've ever been but even with that sometimes I walk like a drunk man and can't do any kind of task requiring fine motor control efficiently.

10:15 I work with appliances and while the refrigerant put inside those fridges may harm the atmosphere, 1. they shouldn't be finding their way into the atmosphere and 2. the damage they cause is very overexaggerated. Just because it can be harmful doesn't mean that it's currently harming the atmosphere whenever you are putting it into (hopefully) a fridge with a sealed system where it is being cycled through. The reason why we hear a lot about this is because the refrigerant industry is using it as a reason to replace all of the old fridges or force people to buy a newer, more expensive version of the refrigerant. This is because it was just getting too cheap for someone to be able to replace their fridge's coolant. Well, you may ask why does that matter? I have seen the results first hand. Customers would come to the store and whenever we told them the price of their coolant they just said to forget about it, that they'd just buy a new fridge. If we did end up replacing it, they often had some other problem not too long after we got done replacing it. Now, this could be because the fridge is old but it could also mean maybe the new coolant isn't playing nice with the fridge as well. Either way, the company wins. They either sell very expensive trashy coolant or a whole new fridge. Whenever we go out to repair them it's a similar circumstance, and some people just can't afford it due to their living circumstance. It's really sad. Additionally, because of this, you get a bunch of fridges that people throw away (creating trash) that could otherwise have a bunch of useful parts in them. Old fridges used to last for years and the newer ones get thrown away even faster because they aren't worth a flop.

I really like the analogy of infections being like wars with collateral damage. I learn so much from this channel!

[@xaviotesharris891]

Really pleased that while I served in the U.S. military, I was vaccinated for virtually everything. Also pleased with never having had a seriously bad reaction to any vaccine. Just sore arm syndrome, with an occasional fatigue and very occasional light fever.

Would be cool to see a pregnancy video and what it does to the body over the months. Because being pregnant also lowers your immune system.

[@A_Stereotypical_Heretic]

Yeah no that's not true. The most recent research shows the opposite.

[@thunderspark1536]

@@idontneedaname318 It's likely that the body reinforces itself to protect the baby, while still putting a ton of energy into said baby, making it seem like the immune system is weaker overall, while the baby's is supercharged.

I would love to see a video that specifically covers autoimmune diseases. Maybe explaining the difference between allergies and autoimmune diseases in a digestible way. That's something I can never seem to get people to understand which I had hoped would be covered in this video.

[@123FireSnake]

In the "training" part you should've mentioned a generally healthy life style as well. Vaccines are all fine and dandy but rely on us knowing what's comming our way. Working out, not smoking, not being obese, ect. all the things that contribute to a healthier body are catch all's aside from their various other benefits and should definitely be covered when you have a dedicated part about increasing the immune systems efficiency.

[@iainbrady3629]

Definitely should be the focus of all health. There's not enough stress on the proactive nature of living a strong, healthy life. People want to look for an easy fix like getting a vaccine or taking medicine, which can help, but is at the end of the day, not the most resilient you could make your body.

[@123FireSnake]

@@iainbrady3629 Indeed, sadly most people these days look for the easy fix in everything. Ups and downs of progress i suppose, we're so well off that there are easy fixes for most problems so people don't even have to learn how to deal with real issues anymore.

[@DrunkenRhyin]

It makes sense that they would focus on vaccines. Many people have been discounting how much they can help over the last 3 years. A healthy body is always good, but as the video points out - you don't know whether your immune system may be strong against some diseases, but weaker against others until it is put to the test. Many extremely healthy and fit people such as athletes and gym trainers still succumbed to diseases like Covid. My friend who runs marathons, attends sword fighting classes, and is significantly more fit than I am responds horribly to Covid, where as my family is lucky and doesn't respond much to it at all. Its a roll of the dice.

[@123FireSnake]

@@DrunkenRhyin It's not though, if your friend was less fit, maybe even obese he'd keel over and die... If he has that rough of a time with covid, so depending on quit ehow rough it was him being that fit might have saved his life.

[@DrunkenRhyin]

@@123FireSnake Yes, but lots of people over the past 3 years talked as though healthy living alone would protect you when its not enough. And between healthy living and vaccines, people discount the value of vaccines more.

[@Isdac1]

Wish you guys had covered the different types of vaccines and the body response to each.

The way they explained it as a video game really makes me want to attempt a no assists run. 😂

[@Fleetstreetbestone]

I’ve been watching these guys for a while now but I find the fact that they didn’t even mention having a healthy lifestyle which has been proven to immensely boost your immune system and health in general, quite disappointing. Eating unprocessed, natural, healthy foods while getting regular excessive can decrease your chances of dying to illnesses drastically, I mean just by not being obese you are 40% less likely to contract covid when exposed to it. The fact that 41.9% of adults in America are obese and they didn’t even clarify this in their video, only focusing on vaccines despite the covid vaccines being very controversial due to the shady nature of Phzier and the censorship of information on lobbying ect. and also 16.0% of female participants reporting LTAEs which were mainly fatigue, menstrual disturbances, myalgia, arthralgia, dizziness, and headaches, is just shocking and seems misinformative to be putting this out.

I was once brought to tears reading the Wikipedia page for smallpox, for the simple fact that it is written in past tense. Like, "Smallpox was a disease that killed 20% of those who caught it. It was a menace for humankind from time immemorial up until the 1970s." How much can one wish that the articles for polio, measles and many other awful diseases would one day be converted into past tense too.

[@TheSpecialJ11]

This makes so much sense. I got COVID this past December after going three years without getting sick, and now have been sick twice since. My system totally got weakened and hasn't yet recovered because winter takes such a toll on my health.

There's no such thing as a cold and flu season its a vitamin D3 deficiency season. Take some vitamin D3 and K2 with food and eat healthy and maintain a healthy weight you won't get sick so often.
