4:50 yes he did correct himself in his recent video on horses, horses are also long distance runners who sweat too, but they don't sweat as efficiently as humans bc they still have fur even if it's short.

Talking about the stamina thing, hunger is a hell of a drug. Back when we were hunter/gatherers, we could turn off that voice in our head that said "stop." Mainly, because we knew if we didn't kill whatever we were running after, we would die.

I love the fact that you actually have a list of animals you don't trust lol

TierZoo is kickass. Was fun seeing someone experiencing it for the first time.

TierZoo is a great channel. This is the first time I've seen anyone react to them. Thanks.

As a former distance runner you are correct. It is just as much mental as it is physical you do get to a point where you just keep powering through it until your body finally transitions over to burning fat after burning up its easy energy stores.

Hearing an incredibly in depth and intellectual point being made with video game terminology was something special. Truly unique, very interesting and retaining. This is a format I would watch again, that's for sure!

3:05 I can confirm that. When I started running to lose some weight I usually run 7.5km in one go but at one time I was struggling and decided to push even further, after I reached my marked, suddenly I felt like I can run forever, so I run to 10.5 km mark and stopped only because my feet were hurting, skin pale of on them which made the open area fee burning on a contact with my shoe. When I stopped I literally felt my blood flowing inside my veins, I don't remember exactly, but in my memory, it was as if you could've heard and seen it pumping from the outside of my skin. Damn it was a wild feeling, I think you are right about the statement that if you push past "I can't do it anymore" your body enters a special state which allows you to push even further

The dinosaur, insect, and bird tier list is in my opinion the best videos I’ve seen on his channel.

Your videos truly are the highlight of my every day. The way you said “I know chims throw things… usually feces” and then looked away from the camera had me dead

Tier Zoo is one of those channels where it's definitely worth watching all of their stuff.

Seriously love the chill af vibes you always bring--- and you continue to have amazing taste as always 😎

My opinion on the sweat being unique to humans part is it was referencing the effectiveness of it just as throwing is leagues better in humans than in other animals (I'm just speculating though).

"YOU'RE JUST WEAK !!" So unexpected, I'm still laughing 😂 thank you

the running thing is 100% accurate. when i first joined the army i almost blacked out running a 8:30 mile, and i had asthma it felt like i was dying. by the end of a year of running 3-5 miles every morning and up to 100 in a week for a bit, i was running 5 miles in 30 min and just feeling like i could easily keep going. every human who is not disabled or morbidly obese should be able to run atleast 2-3 miles within 30 min. train for a few weeks or months and you'll be passing 5 miles in under 7-8 minute miles easily because thats what your body is designed for.

What a coincidence; I've started reading the book Sapiens three days ago. Your channel is such a gem. I'm glad I found it. Keep up the great content!

If you're looking for other channels to react to, I recommend Kurzgesagt and CGP Grey. Both of them are educational channels, but in different ways. Kurzgesagt does space, earth sciences, and existential despair about being one tiny mind in a vast and uncaring universe, and CGP Grey does hyperspecific videos on history, technology, and airports (seriously, he has three videos on minutiae of airports and they're all fascinating). They collaborated on a pair of videos together, which I recommend as a starting point: "What Are You?" on Kurzgesagt's side and "You Are Two" on CGP Grey's.

As someone that can only jump rope for 30 seconds before getting massive chest pains followed by getting drenched in sweat and arm numbness I'd really like to have some of that OPness.

Thanks for another great video. We lost our speed when we stood upright on two legs. We may have more stamina, but there’s no way we could outrun a cheetah. I don’t intend to personally prove that…. And yes, you’re right; horses do sweat.

All mammals are descended from ancestors that had sweat glands, although I'm guessing that some (I'm thinking of whales) have lost them over time. I think it's more a case of sweat being a more effective cooling mechanism if you don't have fur, rather than other mammals not having sweat glands at all. My favourite video from this channel is "Earth's Worst Balance Patch".

You're right about Horses also sweating, it's just we do it better. As for more recommendations from TierZoo, i'd recommend just having a gander through his videos and picking one that interests you as that way we all get what we want :) Though, one of the channels he previewed in this video is called Primitive Technology. I also highly recommend this guy too, especially if you're interested in how primitive humans might have achieved certain things. Primitive Technology is the channel that basically started the 'Build a hut in the woods' trend that cropped up a few years back, the major difference being that John of Primitive Technology actually does everything with the tools he's made himself. Essentially at the start of his channel he is just a man with a pair of shorts in the woods with a camera. But yeah i definitely recommend watching a few of his vids, markedly the tiled roofed hut from 7 years ago (holy bologna that makes me feel old) but again just any that catch your fancy would be good. For comedy i'd recommend Ryan George, he has a pitch meeting series and many other sketches.

TierZoo is great for learning more about random animals on a more generał level (with some exceptions) and the game-like narration style is awesome. Another great channel is Ze Frank and his “True Facts” series. It’s incredibly informative, uses unique, scientific footage and Ze Frank is also an extremely funny guy. I think you’d love it. 🙂

Yesssss more Tierzoo pls. Such an underrated channel that only has like 4 people reacting to it on KZfaq for some reason lol

Tierzoo is fantastic, presents genuine animal/biological education in an MMORPG style making it easier to understand

On your bit about the conversation with your friend. One thing to keep in mind is that fast walking and jogging also count towards this endurance, not just full-out running. Hunter-gatherers generally walk at a brisk pace or jog, rather than a full out run, which is way less efficient. Then they use their tracking abilities to keep track of the prey when it is out of sight. With humans, walking is pretty much a resting state. So even while we're resting, we can still be moving. So if you are running 2 miles, but had to slow down and walk several times throughout, that still counts towards this endurance. Though there's definitely something to be said about reaching ketosis, which I imagine hunter-gatherers do much more frequently. IIRC, humans have one of the most powerful systems of ketosis, and that most animals aren't efficient enough to keep moving while in that state. Meanwhile we can still keep up our usual pace. But you still don't need to be in a full run to take advantage of ketosis. It might be the difference between running 4 miles and 15 miles, but it can also be the difference between walking 10 miles or 50.

I choked on Christmas dinner when you said: "You're just weak!" Pretty sure I have part of an au gratin potato lodged in my lung. 😆

Nice! I was actually thinking of mentioning TierZoo when you did your Casual Geographic video but it appears you've found it all on your own. Cheers!

been watching this channel for around 3 years now tier zoo is witty and informative you wont regret watching more. id look for the early video which sets up his simulated game theme of patches and dev updates and tells the story of early life

Can't go wrong with a good POV video. Thanks for the fun content!

Wow, I didn't expect you to react to tier zoo! You should definitely react to more of this channel's content! A good second reaction could be to one of the other videos they have about humans!

I did not expect this react, definitely enjoyed it

Reading sapiens rn, and didnt know about the inaccuracies. Gonna have to look into that! Also, Tierzoo is one of my fave channels. It's such a original viewpoint to see Earth as a videogame. I highly recommend any of the broader class type videos. And btw, in a later video he does indeed correct himself about horses also being able to sweat.

Cool video and a thought inducer. Perhaps that in itself is a top tier quality, we think so much about so many things and sometimes act on those things. Which gives us new inventions, cool. Cool commentary young lady.

You are correct. Horses do sweat. Shows when you ride them hard too not just from under the saddle but by their neck and on their legs. Saw it a lot when doing rodeo as a kid.

I love the fact that you don't have intros. THANK YOU.

That was a good video - fun and good facts too. PS: Hope you are safe and well over there - your weather is crazy right now!

4:35 yes other animals sweat , but no other animal utilities sweat to the degree we do. Dogs sweat as well.

Been watching some of your videos. Good job, you got a new subscriber.

Love your seriousness with which you communicate your list of animals you don't trust haha

Love the TierZoo channel. There are a ton of great episodes that cover a great deal animals ranking and special abilities and attributes that some have that makes a big difference. It is true other animals can sweat but because of fur the evaporating sweat doesn't come close to cooling the animal down the way it cools humans.

" You do have that stamina or you could...you just might not have the mental strength " OUCH 🤣 I'm waiting for your album of dis tracks

I love TierZoo , can't wait for more reactions

When that guy missed the punching bag, I lost it

December 23. There is a huge Blizzard outside. I get to see No Protocol one more time before Christmas. MORE IMPORTANTLY. I get to tell her and everyone on the channel. Merry Christmas.

More tierzoo reactions, this is amazing

Love Tier Zoo!! he's a really fun channel

When I was training for a half marathon, I would do math problems in my head sometimes, which kept my mind off of the suffering from running a long distance. I ended up getting sick, as I was running in the night’s cold. but it didn’t take long to reach 8 miles in 1hr 4 min. Say, 2 weeks, just to throw a timeframe out there. Day 1 I grinded out 2 miles, then went from there.

I read Sapiens it's by Yuval Harari who is one of Klaus Schwab's henchmen, you would find it interesting to look into both of them.

Yes! Been watching these for years. So funny! Also, best intros ever!

TierZoo is really great for general animal types and "deeper" dives on specific animal types

Interesting. Wishing you peace love and joy and warmth this holiday season

Love Tier Zoo vids!

Yeah, he corrects the Sweat thing on his video about horses. Maybe you can react to that one next?

More Tier Zoo! So many good ones!

Bro your intros are getting ridiculously short 😂 I love it though, love from NC!

‘Erroneous’, I haven’t heard anyone use that since I was a kid. There was a poem: Moses supposes his toeses are roses But Moses supposes erroneously ‘Cause nobody’s toeses are poesies of roses As Moses supposes his toeses to be.

“Already started” holy shit best intro ever haha

Props @5:45 "look at Khabib" Knowing the man, and that he fights bears. Impressive, Most Impressive

Horse person weighing in. As a centaur I can confirm we do indeed perspire.

Keep these coming

I remember in high school wrestling , the teacher made us run that day. It was the first time all yr. We had to run 5 or 6 miles all at once around the outside of the school. One guy threw up, but he’d drank the night before. Still, he pressed on. The guy leading could run forever. He must’ve had slow twitch muscles. That translates to less power, but greater stamina.

Absolutely correct that horses, do in fact sweat. I've never seen their head or face sweat like us, but their body, yes.

Running is also based on fitness and loungue/air capacity which can be trained, same with leg muscles

I'd love to see a reaction to " are goats OP"

8:13 those bees be following that M.A.D doctrine lol

Hey I love your videos and attention to detail is it possible to do a video on the science and aerodynamics of formula 1 race cars and how there is similar comparison to flight I believe a lot of people downplay the physical intensity and toll it takes on the human body driving a corner that’s as sharp and close as a nyc block at 140 mph dope vid by the way

I would highly recommend this video. Michael Reeves "I Built a Surgery Robot" Hilarious.

Love your reactions and chill nature. You should react to his bear tier list.

i think you are the only channel there just skup its own intro! :D

Best intro so far! 🤣

I think you are right, not proof but I recall an old saying, "horses sweat, men perspire and women glow" :)

Having been chased out of the dark woods late at night, I can confirm that you go faster and further when in a fight or flight scenario.

TierZoo is by far the best one-joke channel on the internet. You should check out the bird tier list if you ever check it out again. Also, you were right about horses and bees.

Happy Holidays, Nice sweater hope you’re staying warm! Book recommendation: A short history of nearly everything by Bill Bryson

I think another and one of the greatest strengths/advantages that make the human so good is its ability to cook food (indirectly mastery of fire) because it allows for much faster and efficient energy gathering for development and for activities and more time to be productive etc.

Great video! Just out of curiosity, where did you go to college?

Honey badgers are 100% trustworthy. You can trust them to do the most violently chaotic option open to them every single time!

Yuval Noah Harari, the author of Sapiens, did A Brief History Of Human Kind as a lecture series on Coursera back when Coursera was fantastic and free and not the money-grabbing monster it became. I think I may still have the videos somewhere.

Humans have the most effective sweat system he clarifies this later and fixes it in a later video

These are great, thanks.

We need more tierzoo reactions

I don't know why, but imagining her going to Sea World and suspiciously looking at dolphins is pretty funny.

In the study of economy of moving. Such as walking running etc. How much energy it takes to move. Humans are in last place against all other animals. However they can run for a longer time and over longer distances. But put them even on just a bicycle and they move to 1st place.

Merry Christmas Protocol :)

Dolphins are at the top of my list as well LOL. Mostly because people think they're friendly but they most certainly are not.

Tier Zoo Iis great bc of how he talks about features and abilities developed through evolution explained through gaming language like the devs snd the meta. Some videos to check out would the Big Cat Tier list, seperate Continent metas, anything w Dinosaurs, a n d cartoon crossovers. And yeah Horses sweat.

PBS had a program once that posited the idea that what made humans OP was an accidental reduction in the size of the jaw muscle, that made it possible for the brain case to grow very large.

I gotta agree with 2:59 your take on physical stamina. It has greatly to do with mental willpower from my experience, almost as if it's a second backup source of energy, even after your body tells you "ok...that's enough now, you can--hey stop!" I'm no doctor, but would our intellect and self-awareness be a defining factor of our physical advantage? Being able to go beyond through mental fortitude where animals would just heed to their instinct to stop?

I mean right when you said you think horse is sweat I almost immediately thought of the exact same thing before you said it that when I've ridden horses before and taken off the saddle it feels moist under the saddle.

Wow awesome thanks for sharing ⭐ you look fantastic have a blessed weekend

Brevity of your intro has increased to max level ++

Sweat glands are part of the horse's system to regulate body temperature. They are found over most of the body except the legs.

'oh, already started' instant like :)

Love the Tier Zoo channel, fun way to learn with a video game slant. Another fun channel is Real Science, loved their video on the insane biology of sloths. Another good Tier Zoo video is Are Horses OP?

Our ability to throw further, came at the cost of the increased chance of dislocating our shoulders.

Love this i need more

Human sweat is unique. Some animals like horses can sweat too but it's through a different type of gland. Horses secrete a different mixture and their main way of cooling down is still panting.

A note on tool use. Yes, some other animals can use tools to some degree, but human suse composite tools, and that's a unique feature. Taht is - other animals can use stics or stones, but humans learned to combie those, making a new, more effective tools.

"look a khabib." Made me legitimately lol. Fan.

you are correct in the fact that most honey bees die after stinging. the africanized honey bee / killer bee / honey wasp is an excepton to that however since their stingers dont hae hooks and therefore do not rip out once they sting
