  • Hi there - we appreciate that the “just filtered” part of our title has drawn a few comments and we want to address it. First off - you’re right; you could say lots of things are filtered blood products, including urine and even the carbon dioxide we breathe out. We decided to make this video because we believe most people, including ourselves, don’t think about how the same thing is true for a substance a lot of us drink every day - milk from an animal - and that communicating that fact would lead folks to a different appreciation of what milk is. Secondly - you’re also right; we didn’t fully convey the amazing things that the mammary gland does. Almost all of the precursors to the stuff in milk DO come from the bloodstream, but the special cells in the mammary gland transform many of them into their final milky forms, which we simplified in the video as “do some chemistry on them” and in the title as “filtered.”

    • In other words, you oversimplified to the point that it's no longer correct and misleading. Manslaughterers can be called killers too. So are murderers and serial killers, but let's all just simplify them to killers right?

    • Blaze the Dragon so they have to use WRONG terminology? It's not filtered blood...

    • Sebastian Elytron it's not pedantic at all... they are oversimplifying and sensationalizing it. And using the wrong terminology.

  • Dont have a cow, man!

  • Well... bye bye cereal...

  • So do human mothers filter blood to produce milk for their babies?

  • I’M A VAMPIRE EVERYONE!! 🧛🏻‍♀️🦇

  • "Milch is Gift"

  • I wonder how Jehovah Witnesses' react to this video. If you belong to that faith please let me know.

  • So glad I don’t drink cow milk

  • Bitch, don’t you mean titty juice?

  • thats almost cannibalism just add some organs and thats where it goes a bit wrong

  • IM NEVER DRINKING THE FARMERS MILK ANYMORE

  • You can let any food sound disgusting somehow. Disgust is just a safety mechanism and as long as it doesnt prevent you from dangers its completly pointless. So stop trying to achieve disgust and only show the part in which you explain why milk is not really healthy.

  • Fuck u m8... you ruined my fravorite drink bitch

  • I better stop drinking milk so my bones will turn into powder xdxd
