For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

    There is about 8.1 billion people in the world. Assuming romantic cliches to be true and that we all have exactly one soulmate out there, we would have a very hard time sifting them out. If you were to use exactly one second at meeting a person it would take you 257 years to meet everyone alive on earth at this moment, which due to human life span being significantly shorter and the influx of new people makes the task essentially impossible without a spoonful of luck. Moral of the story: If you believe you have found your soul mate, be extra kind to them today.

      Soul mates are made, not found. You get with someone compatible to you, and through the sharing of experiences and affection, if nothing goes excessively wrong, they become unique for you.

      Well I don’t need to meet everybody. There’s no need to meet anyone who doesn’t match my sexual preferences, so that’s half right there. Then we can also cut everyone who’s sexual preferences I don’t meet, as well as anyone outside of a given age range (most of the people on earth are much younger than me and would be inappropriate for me to date). We can probably get that down to about 50-60 years. (At one second per person).

        The thought experiment was just an attempt to show how hard it is to wrap our minds around big numbers. Even a tangible number such as the amount of people in the world.

    There’s a giant ball of extremely hot plasma in the sky and we aren’t supposed to look at it. What is it hiding? Surely if someone managed to look at it long enough, they would see the truth!

    Time relativity always boggles my brain, I accept the fact but I find crazy that if I strap my twin and his atomic clock to a rocket and send them out to the stratosphere at the speed of light, when they return he’ll be younger than me and his clock will be running behind mine. Crazy

      Every time that comes up, I think to myself “Something I’ve gone through must be more painful, right? I’ve gone through some pretty hellish things, and you’re trying to tell me something MORE painful exists? Not just a little more, but dramatically more? For my own sanity, I’m gonna have to live in denial of that.”

    Your bones are made of calcium, which is also a metal. You’ve got a metal frame inside your body.

    There are only 24 episodes of the initial run of The Jetsons and only 25 of Scooby Doo. They got aired as reruns for decades before more episodes were made. There are only 15 episodes of Mr. Bean.

    To piggy back on your “bizarre fact”, the same type of iron can be found added to cereal.

    I remember several times in school we’d do a science demonstration where we’d smash up Cheerio (or a knock off) brand ceral, mix the powder with water and slowly drag a magnet through the slurry. Every time the magnet would be pulled out of the mix, there’d be more and more tiny iron bits.

      Tides are a phenomenon where the height of the edge of a body of water shifts relative to the shore. A phenomenon is a thing. Why should explaining its cause in those terms have any effect on that?

          That’s like saying sunrise doesn’t exist because the sun is relatively stationary while the earth revolves on its axis. Sunrise and tides are the names we give to how we experience these things.

          Subjective experience cannot be wrong or right; it simply is. Interpretation of that experience can be wrong or right. Either way, the experience still happened.

      From Wikipedia on bones:

      Bone matrix is 90 to 95% composed of elastic collagen fibers, also known as ossein,[5] and the remainder is ground substance.[6] The elasticity of collagen improves fracture resistance.[7] The matrix is hardened by the binding of inorganic mineral salt, calcium phosphate, in a chemical arrangement known as bone mineral, a form of calcium apatite.[9]

      So the statement is a bit faulty, not only because of the relative low amount of calcium in our bones, but also because it appears as a mineral. We distinguish between salts and metals because of their chemical properties being quite different (solubility, reflectiveness, electrical conductivity, maleability and so on).

      Edit: I do realize the point of the comment was not to be entirely factual, so if I am allowed as well I would say science is pretty metal.

    Similar metal in the human body one, Vitamin B12 has cobalt in it. Absolutely wild. I guess that’s not really commonly known but it’s still worth mentioning

    The birthday paradox

    If you get 23 people in a room the odds of two of them sharing a birthday are 50%

    The birthday paradox is a veridical paradox: it seems wrong at first glance but is, in fact, true. While it may seem surprising that only 23 individuals are required to reach a 50% probability of a shared birthday, this result is made more intuitive by considering that the birthday comparisons will be made between every possible pair of individuals. With 23 individuals, there are (23 × 22)/2 = 253 pairs to consider, far more than half the number of days in a year.

      it’s not part of the paradox, but there are also days when people tend to have more sex
      like new years, valentines, christmas etc. (in the west at least)
      so you tend to get more people born 9 months after those days

        In high school my graduating class was 38. The one before us was 21, the one after 18.

        Coincidently there was a massive blizzard that snowed everybody into their house for a week about 9 months before my birthday.
