    Thanks for the laughs but I think those are tiny little Ants on your skin Ant not spiders. I was tired and sad this morning but your little bit of fun with the little Ants made me laugh, Antman Petrov and his millions of mini me’s.

  2. Kevin Jay

    Anton, I really appreciate you and your work! Your endeavor in scientific communication is of immense value! Thank you!

  3. Tau Neutrino

    Very good “off topic” episode!

  4. Frank Owsianik

    “Then I think the universe decided; to appreciate life, for there to be change and growth, life had to be short.” [Dialogue from Lorien, the universe’s first sentient being and naturally immortal to Ivanava. Babylon 5 Syfi series.) 🙄

  5. Chinchilla

    Why do I keep on thinking 10 years ago was 2000~.

  6. Jacque Corpoix

    6:27 That gave me mini anxiety attack. Lol.

  7. Joe Causey

    The “animal” in your teeth? LOL! Think that’s supposed to be “enamel”.

  8. Harrisa Mapon

    Anton: So… don’t get too freaked out by all these little spiders crawling all over you………..

    Me: I don’t appreciate being trolled 🤣🤣🤣

  9. Nicolas Kuschnir

    Is there bacteria in our brains? Do they influence our state of mind? Our thoughts and emotions? How much of us is really US? 🙀

  10. WTF Jesus

    Anton, I love you men….but why did you say spiders? 😱


    So our body is basically a living ecosystem. We’re just the captain of the ship.

  12. Brian H

    Interesting to know.

  13. Le Trepidant

    Lung cells: 0.1% renewal… I’m so dead. Oh, well… It was a good life.

    (Lights another cigarette.)

  14. Robert Lawrence

    Things are always trying to eat us but our body regenerates. As soon as we die, the things win. 😱

  15. mlj rotag

    No wonder I’m always so tired.

  16. Kris Kolstad

    Everybody has mites in their eyebrows, you can also get them in your eye lashes, but that’s considered an infection. The mites in your brows live in the follicles and only come out when it’s dark. I bet you’ll have itchy eyebrows tonight!

  17. Artur Emil

    Amazing. Mind blowing.

  18. Picklewiickle.

    The sinoatrial node cells are with us for life and never regenerate they regulate heart rhythm.

  19. Miss Sunshine

    Thank you!! 🙏 Ive heard that about the fat cells too.

  20. buttafan


  21. flyshacker

    Wow! Outstanding episode! Anton is the best teacher!!

  22. Dazanar

    liked this anatomy edition here

  23. Joe Gillian

    2:06 that right thumb looks…very long. Very long fingers in general.

  24. Sandy Barnes

    That explains Dr Who, kinda. 😋

  25. Joseph Paul Duffey

    I seriously suspect that if we can come to a deep understanding of how these regeneration tiers and timers work we can successfully manipulate the total bodily life span.

  26. JD Lives

    I need like 50% more brain cells. To many late nights as a teen.

  27. Meadow Moss

    Thanks! I sure appreciate you!🤗👍

  28. Peter Rabbit

    If you have a loupe with 50x magnification, you can see mites walking around on your skin, like little freaky cows.

  29. Vector Equilibrium

    It all makes you feel kind of wonderful. ☮️❤️🙏🏻😁

  30. Iain Ballas

    I’m sure mom will tell me I could be doing better.

  31. Leandro da Silva Gonçalve

    Okay, we not all cells are replaced in our bodies. But they never speak about the molecular and atomic structure of the body!

    Even if some cells don’t get replaced, they also need to exchange particles with the environment

  32. infinateU

    1 single iron particle surrounded by 3 million hemoglobin to form a blood cell? So, is human feces high in iron content?

  33. mr. creosote

    ooooo that’s a lot of blood cells [looks around and sees 23 erythrocytes

  34. coweatsman

    “Mites are not spiders.”

    Correct but not a million miles away from spiders either. Mites, along with scorpions and spiders are members of the class of arachnids of the phylum of arthropods.

  35. Stuff & Things

    Every few weeks our skin is not “new”. It’s a continuous process. Unless we were like snakes and do it all at once.

  36. Angelus Irae

    Cells at work!

  37. Shaunak Basu

    The secret behind why Anton is becoming even more wonderful person with every passing day 😇

  38. Financial Interferometry

    The mites live in perpetual fear of what they call the coming of the great Luffa.

  39. PsyintZ

    Haha, I love when Anton does those cheesy little intros.

  40. Caden Rolland

    So “New Year, New You” is pretty much accurate.

  41. Joe Eoj

    but how can Marxists function without brain cells?

  42. Charles Adams

    This brings up a question: how many mite cells are regenerated every second?

  43. John R B

    I praise you (God) because I am fearfully and wonderfully made; your works are wonderful,
    I know that full well. Psalm 139:14

  44. NLnaLovesU86

    Mites ! 🐞😥🥺🦀 🥳

  45. Carletto Buracco

    My science professor, first time in the lab presenting us a dozen of crappy microscopes, said “Rule number one: never point a microscope to yourself. You’ll only get years of nightmares.”

  46. didi hols

    Anton: “Woooooow that is a lot of Blood Cells”
    Me: Hits Like

  47. cmans

    Dang. We shed a lot of cells lol

    We’re like…walking cellstorms….get it? Like a snowstorm but with cells…. :p

  48. Paul the Audacious Bradfo

    But why is Dr. Who able to regenerate his whole body?

  49. ChunkyLover69_420BlazeIt

    **covering myself in lighter fluid and looking for matches** ….Spiders…huh, you don’t say…

  50. The Rodestarr

    After learning about those mites, I can’t look at my bedsheets the same…

    I guess its time for laundry

  51. Tristun Alekzander

    They are called Demodex, for anyone interested.

  52. R Carmisin

    Messing with the DNA could give the cells a new trait the next cycle. Fast track evolution instead of relying on your parents traits.

  53. Marcus Munro

    😂 spiders. Excellent video!

  54. MoltenCheese

    So Anton, Star Trek or Star Wars? just curious.

  55. linda gates

    Ha ha thank you for letting me know that I am not covered in spiders 🤷🏼‍♀️🤔🤔🤔🤔🤔🤔😢🖖👍🖖👍🙋🏼‍♀️

  56. malleus maleficarus


  57. Pineapple Owl

    very interesting. ive been trying to uptake optimum nutrition for synthesis and regeneration.


    I have a few less brain cells because of the double vodkas I have on the weekend😋

  59. Geno Stellar

    “So… don’t get too freaked out by all these little spiders crawling all over you.”

  60. LeiionReyn

    I lost weight like 10 times. Quite impressed for myself.

  61. Computer Garage LLC

    well, that explains all the dust. LOL
    spiders, ofcourse.

  62. али маах дей

    Mistake at 7:36 . It’s approx 2kg of bacteria, not 0.2kg

  63. eric vulgate

    Passersby were amazed by the unusually large amounts of blood

  64. Alfa Centauri

    Ok, so after losing weight you need to hold on for another 10 years for the old fat cells to vanish.

  65. Martin Olsen


  66. james robinson

    Lol Anton, you really shouldn’t have said spiders!

  67. Golden Shine

    Anton always has an interesting topic.

  68. Gerrie

    Hello Wonderful Anton :o)

  69. L M

    Thanks Anton. Nice change of pace.

  70. Black Pullet

    When I had leukaemia I needed to replace my white blood cells by getting regular blood transfusions. The time between blood transfusions was about the length of time that those new white blood cells live — 2 days to 1 week.

  71. MC's Creations

    We are, each of us, a multitude.

  72. phillip testerman

    Anton: speaking
    His body: *regenerate… REGENERATE*

  73. Brikx

    THANKS ANTON! I hate spiders!! lol

  74. Kristi Deanda

    Is that why I get random itches in dry skin areas?

  75. Johnny Johnjohn

    Exponentially fewer frequencies that regulate those cells though. And by frequencies I mean emotional states.

  76. Monke. :D

    Wish you were my science teacher

  77. Mihail Colun

    Where is all that blood going?
    To the d…

  78. Simon Gough

    Ahhh im covered in spiders. 😆 😀😀

  79. NewCreation

    Roughly 20-30 trillion red blood cells traveling through 60,000 miles of blood vessels. It gives a good idea of the size of these structures.

  80. Derian Vandalsen

    6:30 Time to scar(e) the arachnophobics😈

  81. Fake Name

    I thought the brain does regenerate, and that the main problem was damaged tissues not being able to be removed.

  82. Prateek Chakraborty

    Appreciate your work bro..everyday a new video is not a joke.

  83. Keny Charles

    I feel like I’m a new man every morning! I must be doing something right.

  84. Farrier

    Hooraaay! It’s been scientifically confirmed that I will eventually be able to shed myself of this lockdown lard.

  85. James Samples

    That explains the 80 grams of fresh dust piling up on the guitar I’m supposed to be practicing on. Now I know. Great videos! Thanks!

  86. Lars Richards

    ‘There are constantly crawling spiders on you’. That freaked me out. I now probably can’t sleep!

  87. Sam Harper

    I am so relieved to find out that fat cells aren’t forever. Now if I can just stay skinny for the next ten years.

  88. Bob Master

    There are thousands of spiders on you right now but dont worry about it.
    Me: 👁👄👁

  89. ☺smylyface☺

    Hello wonderful Anton!

  90. John Smith

    You did it again Anton :-)

  91. Cy Simi

    As someone who struggles with body image and persistent workouts, I really needed to hear this today. Thank you, Anton!

  92. Bruce Daniel

    Shouldn’t the egg cells in the ovary be on the list of cells that don’t regenerate?

  93. Benjamin Kallestein

    Great to be early! 😃

  94. xxjohngamer

    the 15th one to comment i guess

  95. Aaron B

    I’m really fond of my blood cells. :)

  96. Cornbreadfed kirkpatrick

    Not being mean I know some people don’t regenerate brain cells.

  97. Mr. Typer

    hello wonderful person

  98. Bubba Allen

    I wonder how long before we can put them all on pause for cryo stasis!

  99. Astrophiliacx

    It’s a bloody mess everywhere!💉🩸

  100. xm11
