      I imagine this being said like the guy in Bill Nye the Science Guy

      And knowing is half the battle.

    • G.I. Joe

      And knowing is half the battle.

      • Bob

        Sooooo. 60% of my brain is fat…. and 75% of my brain is water…. I wonder where the other negative 35% comes from?

        • blurp

          zombies eat brains… so you're safe

    So that's why those light bulbs pop over peoples head when they have an idea.

    • tv_paul

      I thumbs myself down for screwing up the first posting. Does anyone know how to remove a post when stuff like this happens?

      • PDiddily420

        I think you have to set up an Intense debate account in order to edit and delete comments.

  • LucretiusCarus

    #2 And approximately 25% of the cholesterol in the human body is located in the brain.

    • Slappy_McGee

      That sounds like a challenge.

  • iu chiver

    so its 20% oxygen, 75% water, and 60% fat

    • LucretiusCarus

      The "facts" aren't properly worded. The brain is ~75% water by weight and of the solid tissue as much as 60% can be fat (because of the large amount of membrane).

      You just didn't read properly on the oxygen one–it CONSUMES about 20% of all oxygen in the brain primarily because glycolysis/oxidative-phosphorylation is the only power source in the brain.

      • Trig

        Ohhh! Check out the big brain on LucretiusCarus!

        • LucretiusCarus

          That's right, the metric system.

          I paid attention in biochem class

          • SatbehindLucretius

            I cheated off of you in biochem class

            • LucretiusCarus

              You're welcome.

      • Critic

        Ohhh! Check out the lack of a sense of humor on LucretiusCarus!

        • LucretiusCarus

          It was funny when Trig did it. You…not so much.

    • Dave

      Fat cells have water in them, genius.

      Water is also 1/3 oxygen too.

      • Wrong

        Water is 2/3 hydrogen

        • Dave

          congratulations on working out that 3/3 – 1/3 = 2/3

          idiot

          • Wrong

            Trollolololololol

        • Rob

          By mass, hydrogen is 1/17th of a water molecule.

    • johnny depth

      and 155% of accurate math

      • Don_Aguelo

        15% more fat than the average Russian

      • I likey science

        Oxygen = 16 Atomic Mass Units
        2 Hydrogen @ 1.01AMU each = 2.02 AMU
        Therefore, H2O = 18.02 AMU
        Ratio of H per H2O = 2.02/18.02 which means……… drum-roll for this thrilling and exciting fact that is about the be presented… H20 is about 10.2% by mass hydrogen!!!!!

        I does the math much more gooder then all of you all you. DERP.

    Who yawned when they read #18?

    • Rafael-RS

      i did but i wanted to before seing the picture
      true story

    • Geaux Tigers

      WHY DOES THIS PICTURE MAKE ME WANT TO YAWN?!?!?!?!

    • therealbuckfoston

      likewise, i'm sure

    • xbod

      Guilty

    • cjdamien

      this guy did, twice.

    • KyleGamgee

      Nope.

      • Polo

        I yawned after the first 'amazing' fact

        • SadeShadz

          lol

    • Dave

      #18 is simply bullshit. Science does NOT think that at all! 'Send more O2 to the brain' it has to go into the lungs, through arteries etc. by the time it gets to the brain it is NOT cool at all – it's body temp.

      The fucking human race disgusts me. Anyone who doesn't do anything scientific in their lives is a fucking retard.

      • JHL1

        Dave's not here.

      • Duh

        It didn't mean literally cool it down temperature-wise, fucktard… I know, science is hard. Go back to hating on the internet… Much easier.

      I was going to say that! lol

    • SadeShadz

      ME! >.<

    • Underbaker

      Oh oh oh, I know this one!

      You did!

    • MeIrakly

      I just realized i did :O

    • Leeroy

      This fact is wrong, oxygen doesn't increase in the body when you yawn, you don't feel more awake either… Think about it, you feel more tired when you yawn. It is more recently found that chimps yawn to signal a whole family that it is sleep time and this is believed to translate into humans, hence why yawning is contagious.

    • Ass Grease

      I farted. I guess that's just a backwards yawn.

    • nadaal

      I did.

  • BigRedGoat

    #2 #10
    140% of Russians agree!

    • bhvygc

      sounds legit

    • KyleGamgee

      Fat must contain water.

    • Giggity

      Exactly. Maybe.

    • fendermallot

      60% of the time, it works everytime!

    • Joe

      Exactly how can this be possible? I think its all Bull Shit

    • Yames

      beat me to it… Yay for math…

    • grog

      also, whats up with magnets?

    #16 Haters gonna hate

  • zencat

    How can the brain be 60% fat ans 75% water? I call bullshit on this post

    • NOLA

      60% of brain mass which is solid (not water/fluid) could be one way/

    • slaytan

      Because fat also contains water so some of that 75% is contained in the fat as well as other parts of the brain

      • Fathead

        'fat also contains water'

        Oh lawd help me.

        • Chelmsford Spuds

          LOLz maybe be they mean water contains the fat? Jesus wept…

    • maraloc

      Not only that, but claiming that the brain has more synapses than stars in the universe is bullshit too. We simply have no idea of how many stars are in the universe.

      • JPZ

        The nerdified answer is… latest estimate is 3 to 100 x10^22 stars in the universe, which is obv much greater than the 4 x 10^15 the article said. BULLSHIT!

        • Fish

          I think it means 'visible' universe, or it could be crazy hyperbole;

          Still, better than that one which said "our brains have more connections than there are atoms in the universe", which was just plain retarded.

  • BabyFarts Magizax

    #9 holy smokes

  • Sarah

    Its 60% fat and 75% water?

    • DubCitySin

      60% of solid mass fat?
      75% of liquid mass water?

      just a thought?

    • monocogger

      maybe one is by volume and the other by weight? Dunno.

    • Silly Woman

      Don't you know that trying to do math is just Satan's way of distracting you from your duties as a female.

  • M.O.T.

    #2 #10
    And the other 40% is made up of green goo. True story.

    • SMT

      That's Possimpible!

  • anony

    #18 admit you yawned

    • j22

      i did. no bulshit.

    • Underbaker

      I did not, I play that game with my wife all the time and I win (about the only thing I ever win).

    • sploodge

      If you pay attention, you'll notice that there is an identical post just a couple of spots up… Please don't take up valuable comment space.

  • still pissed

    She's still pissing me off chive- hot chicks to drool at please…

  • http://twitter.com/geurtr @geurtr

    Are brainfarts caused by eating to much fatty food ?

  • NOLA

    What does #8 mean?

    • Dan

      neurons are more tightly packed b/c of more connections which increases density. they usually have more mental flexibility as a result

    • dub

      Yeah I'm confused on this one too. It sounds like my Mexican baby wrote it.

      • socalmarti

        !gente ignorante!

    this is why we have headaches when hungover. your brain sacrifices water for other organs and shrinks.

    • BostonChiver.

      If you take 2 potassium pills, or eat a banana, before sleeping and upon waking you will reduce your hangover pain and recovery time greatly. Truth.

      • CaptainInsano

        That's assuming I don't throw up the banana

    • Black6dog

      Tip of the day kids: drink a bunch of water before you pass out and you'll substantially reduce your hangover if you have one at all, true story

    • weiner.

      untrue. you have a headache when the lining on your skull loses water. As the post said earlier, your brain doesnt feel pain so if it was dehydrated it wouldnt start hurting….it hurts when it moves around and your skull isnt protected by its normal lining.

      • Mrs_Conejo

        I said nothing about the brain hurting.

        • weiner.

          you said your brain loses water which give you a headache. usually when pain results from something happening to an object, its the object that hurts. (ex-you bang your knee, its your knee that hurts.) therefore by saying if your BRAIN loses water, its your BRAIN that hurts.
          its your skull lining that loses water.

  • Ali Ackbah

    bbBBBBBBBBRRRRRRRRAAAAAAAAIIIIIIIIINNNNNNNNNNSSSSSSSSsssss

  • tom

    "consist" not "consists"

    • sploodge

      grammar nazi gonna hate

    • Chris

      That doesn't even make sense in that sentence.

  • Matt

    And knowing is half the battle, GI JOE!!

  • The Brain

    the brain doesn't stop growing until in the mid twenties, 25 or so, definitely some solid internet facts on this post

    • therealbuckfoston

      well, if its on the internet, it must be true…

    • Black6dog

      That, and #15, your brain's ability to communicate doesn't slow down, it's just like having a conversation with people before and after you're drunk, the other people don't make any sense and you have to repeat yourself a lot

    • Michael

      It may be talking about physical growth, which stops at about that age. The brain continues 'developing' until about 25, you're right…

  • BostonChiver.

    • Tdawg

      I wish i could give you 100 thumbs up for that

  • Einstein

    So according to #2 and #10 our brains are 135% fat and water

    • Hunter X

      dumbass. Fat is 90% water. you no math so good.

      • Spence

        This post no math so good. #17 40,000 times 100 billion would not give you the correct number of synapses… they share connections, so you can't use basic multiplication.

        • Groggy

          It also assumes that we've pegged the size of the universe and the total number of stars in it. That's retarded.

    • therealbuckfoston

      guess again, einsteen;

    • simondoyle1988

      fat is made up of a lot of water so that one is ok but there are a few that dont make sence

    • jegarrido10

      if you add another 5% its a completely 140% russian brain

    • Meatsim

      Fat contains water.
