You are not a person, you are a planet, made of roughly 40 trillion cells. There is so much of you, that if your cells were human-sized, you would be as big as 20 Mount Everests. For your creepy-crawly inhabitants, this makes your body an ecosystem, rich in resources and warmth and space. A perfect place to move into and have a family. While some of these guests are welcome, most are not. Your immune system is the guardian of this planet, the force tasked with protecting yourself against the constant danger of invasion.

    Hey everybody! Today finally marks the release of “Immune – A Journey Into the Mysterious System that Keeps You Alive”. The book I’ve sorta started writing a decade ago!

    You can get it here: – It’s available in English and German and at online retailers it should be available in pretty much all countries too.

    First we had to push the release back because of cargo trouble and then because so many of you pre-ordered that we didn’t have enough copies for the original launch day! Thank you so, so much for that!

    Tonight I’m doing an AMA on Reddit where you can ask me about Kurzgesagt, science communication and of course the book! Join here:

    In any case – Kurzgesagt is a passion project and it’s just so heartwarming how wholesome and supportive our community and viewers are. I’m incredibly grateful to have this job and to be able to make content for all of you, video or printed. – Philipp

    I haven’t worked out in a while, but damn. Me needing to go to the gym, wasn’t what I expected to learn from this video.

    “Immune is fun and great to look at, and it even SMELLS GOOD!”

    Yeah, smells really selling😂

    • Jackson Funke says:

      Ok, I was at the end of the video and scrolling down as he talked about the book, and then I read this comment, was kinda confused, and then within 5 seconds of reading the comment I hear “Immune is fun and great to look at, and it even smells good.”
      The timing was uncanny.

    • Alist's Heart World says:

      @jayzenstyle Yeah I know right 😂

      But that’s not what I mean, but it’s okay, nevermind

    • Alist's Heart World says:

      @Jackson Funke Lmao sorry, I only typing what interesting for me

    • Tim Williams says:

      Yeah but now I need to know, does it just have that nice new book smell, or did they actually add something? 😀

    • Alist's Heart World says:

      @Tim Williams BHAHAHAHAH! XD

      It might be

      And if it’s true, I will wipe this book all over my outfit everytime before I go outside rather than using my perfume XD

    i just heard kurzgesagt call babies useless: “and even then, it will take them years for them to be remotely useful”
    my life is now complete

    Biotechnologist here, working on antibody engineering. I have been watching your videos almost since the beginning and preordered your book. Your videos never fail to amaze me, but this video is on another level. Is the pinnacle of science divulgation, something that scientists should aim for. The systems you are explaining are complicated even for those with biology knowledge, but you explain them with an easiness and preciseness worth of mentioning.

    Thank you so much for your videos, and keep it up! 😀
