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.

    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.
