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.

    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!

      I’ve seen some of its secrets during the eclipse. It’s an angry, writhing tentacled thing. Be thankful it’s so far away.

    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.

    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.

      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.

    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

    Here’s one: Iron doesn’t have a smell. It acts as a catalyst in the reaction of bodily fluids or skin oils, which is why you can’t smell coins after washing them

    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.

    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

    Queuing theory can have some fun surprises.

    Suppose a small bank has only one teller. Customers take an average of 10 minutes to serve and they arrive at the rate of 5.8 per hour. With only one teller, customers will have to wait nearly five hours on average before they are served. If you add a second teller the average wait becomes 3 minutes.
