    At this very second, you are on a narrow ledge between life and death. You probably don’t feel it, but there is an incredible amount of activity going on inside you. And this activity can never stop.
    Picture yourself as a slinky falling down an escalator moving upwards - the falling part represents the self replicating processes of your cells, the escalator represents the laws of physics, driving you forwards. To be alive is to be in motion but never arriving anywhere. If you reach the top of the escalator there is no more falling possible and you are dead forever.
    Somewhat unsettlingly, the universe wants you to reach the top. How do you avoid that and why are you alive?

        Entropy does not equal death, it’s just a gradual state of disorder

      Mr Duck, I dont feel so good

    5. Tristan Poh

      Uh does anyone realise that the music linked in the description isnt the right music? I'm quite sure the soundtrack in this video is not the same as the one from emergence...

      1. Tristan Poh

        I just really need this soundtrack lol it's so good

    6. Twitch_StarLord_

      Ah yay Nicee. Thanks alot for another vid. Helps alot during lockdownn!! "Why are you alive?" > Ah now I know why I got this so quick xd ~Random Discord ★St☆rry♕

    7. Sir Franzelot

      shouldn't the falling part of the slinky be physics and the rising part of the escalator self regeneration? Kinda feels counter intuitive the other way round

    8. Mark A

      "If you're bored for SOME reason" *Wink* :D

    9. Boen Wang

      I never thought I would see Omae Wa Mou Shindeiru in an educational video

    10. A1 Ulysses

      Kurzgesagt : Omae wa mou shindeiru Nani?!! Me: oww i see your a man of culture

    11. Silver Vibes

      I love the Easter Eggs in this video

    12. Ashutosh Kulkarni

      "To be alive is to be in motion but never arriving anywhere."

    13. EPICDUDE365

      So if the metaphorical slinky reaches the top of the metaphorical escalator, we die, but what if it reaches the bottom?

    14. jroid3

      that new intro was sick wth

    15. Purple Diamond

      When he said "Biggest anime betrayal", I felt that.

    16. sivaprakash reddy

      Lmao....i like how you used 'Omae wa mou shindeiru.'

    17. Ahmad El-khatib

      This video didn't answer the question right. Perhaps because the question has been asked incorrectly. What is the difference between an old man that is alive and two seconds later he is dead. The cell structure is the same, atp amount is the same, the condition is all typical yet he is not alive. And even if you recreate a perfect cell entirely synthetically in a lab and provide it with ATP it will not be alive. This is the real question. Answer me please?

      1. Ahmad El-khatib

        @Frazs Well my question applies to brain cells as well so I can't comprehend your answer.

      2. Frazs

        In case of the man its probably brain cells, when brain is damaged it cant make organs work, while the cells which make the whole body aren't instantly dead the brain which makes the man is non functioning. Meanwhile, for the cell in the lab usually a thing is called alive because it performs metabolism, thats why things like viruses are not really considered alive, you can sustain a single cell if you provide it with the chemicals it needs to live e.g. Glucose/light/water.

    18. S ᓰ ᒪ ᐺ ᘿ ᖇ

      We understand how life works but we don’t know why dreams occur. We should look into the brain more and maybe we can figure out how death works.

    19. AwsoGlitch

      Life energy is Mako! The lifeblood of the planet!

    20. Dinosaur 1978

      When doctor cell number discovered the atp it made an astonishing discovering.

      1. Dinosaur 1978

        In the year ****** the cell number ********** killed another cell for it's atps and glucose cell number ********** was never found and cells ask for justice for cell number *********;

    21. Alex Doan

      "All life is based on the cell" is an arrogant statement, we have no idea yet whether life exists on other worlds, in other forms. For a scientific channel this kind of thing is not excusable

    22. //Mocha Gacha\\

      ATP = A Teacher's Point

    23. Aaryan U

      <a href="#" class="seekto" data-time="480">8:00</a> did I just spot a f**ng JoJo reference in Kurzgesagt?

    24. Rice Cooker

      In a way it’s unnatural to be alive, but natural to want to continue living.

    25. Al Ash


    26. GinHindew110

      They totally missed the chance to add "it became Perfect Cell" when it absorbed the mitochondria

    27. P Ramchandani

      Kurzgesagt: why are you alive Me : sobs in silence

    28. jh198713

      So that's why plant life is not as complex as animal life? Because with the extra energy from the mitochondria we had an advantage allowing for more complex evolution? That's really interesting and it does make sense.

    29. Justin Fowler

      Ha ha. <a href="#" class="seekto" data-time="152">2:32</a> Wilhelm Scream!

      One day my consciousness will merge with the great abyss indefinitely and i will live through the forces of nature and space-time

    34. BlueM00n

      Can you talk about C3, C4, CAM plants?

    35. Darkness117

      So this is why life is so hard to find in the universe.

    36. reyansh agrawal

      What are the next new forms of us going to be?

    37. garvit prajapat

    43. Mukuhi Kawasaki

      The sun is a deadly lazer Not anymore there's a blanket

    44. Tony Arcos

      but what happens when the slinky gets to the bottom of the escalator?

    45. Shu Liu

      So long story short the universe is the biggest killer of life in itself

    46. Rosh Potato

      Best channel for scientific facts and explaining things. Keep doing videos, you are the best

    47. Natsu Crazy

      I don't know how i feel about being a very fleshy cyborg

    48. king_88

      Weird I cannot possibly think of a reason for disliking these types of informative videos. Still some people do apparently.

    49. Sarah

      the last thing i needed during quarantine was to find out the universe wants me dead lol

    50. TommyVallonTV

      Yeah, anxiety

    51. Kevin Vargas

      It's weird hearing the narrator saying memes in a professional style video

    52. Josselin Suire

      To pass butter apparently ...

    53. TheRevivist

      My science class would remember ATP by "all the power" because power is energy. Kinda cool tbh

    54. M4R

      After Joe Rogan if Kurzgesagt leaves to Spotify, NOsel is finished.

    55. Im Gay but

      I'm asking this everyday...

    56. M. Nicoli

      <a href="#" class="seekto" data-time="300">5:00</a> I just love the nerd and meme references. 😂😂

      Wow... this is deep 😐

    60. Abu Dina

      @ <a href="#" class="seekto" data-time="290">4:50</a> he talks about some cells learning... so who was the teacher?! And if the answer is evolution then now did Mr/Mrs Evolution conduct the training?! 🤔

    61. I VisiBomb I

      why cant we just move forward from the escalator and fall forever? are scientists not aware of that option?

      1. Say Sike Right Now

        I VisiBomb I Ohh yeah why didn't anyone EVER think of that

    62. enxvictoria

      The graphics at around the 6 minute mark gave me so much nostalgia to a game called spore!

    63. ENDER 5U1T

      The first Cell to eat sun energy be like: "It's raw"

    64. Peeper

      "and this activty will never stop" *_video stops to load more frames_*

    65. Neltins

      Jesus... so that's why sleep is so important... and why I feel like I have no energy and eventually become lifeless after 24 hours with no sleep.

      *Pretty tasty!*

    67. taratara966

      Where are Russian subtitles?((

    68. KhaZM

      You don’t often hear the words ‘anime betrayal’ and ‘evolutionary history’ in the same sentence

      We are a descendant of a legendary cell that said once said to itself “ Killing is not the answer for harmony is the key to all life” I always knew I was kind to others through a bloodline

      Everything is energy. Our thoughts are energy. We have the power to change our environment with our thoughts. Its all nothing but energy to be harnessed.

      What happens if you go to the bottom of the escalator? Can you?

    77. brianher67

      So if I found everything my body is made of and then create it in a lab and pump it in my body I would live longer? Cells and all

    78. bugman bugman

      I think this might possibly be the dumbest comment section I've ever seen on youtube. This video is diving deep into the mechanics of life on earth, but instead of talking about that everyone is instead pissing their pants over the fact that they said the world "anime" for a split second.

    79. benjtheman

      Statistically, someone died while watching this. Their slinky stopped.
