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.

    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

    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!

    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.

      I used to be like this, but with movies. When I first met my wife, she was utterly baffled at the concept of somebody not enjoying movies, and she made it her mission to make me enjoy them.

      Come to think of it, she actually doesn’t like music much. I’ve failed to change her opinion on that though because my taste in music is shit (and I’m proud of it.)

    There’s no such thing as tides. Gravity holds the water as the earth rotates

      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.

    The sun could’ve gone nova 8 minutes ago and we wouldn’t know for another 20 seconds or so.

    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

    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.

      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.”
