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.

    Don’t know if it’s bizarre but I was shocked when I found out I’d been lied to my whole life… a leap year isn’t every 4 years.

    So leap years happen when the year is divisible by 4, but not when the year is divisible by 100 but then they do again when the year is divisible by 400.

    So the year 2000 is a perfect example of the exception to the exception. Divisible by 100 so no leap year, but divisible by 400 so leap year back on…

      I wouldn’t exactly call it a lie, but more that most people don’t want to bog down a kid in the details (or don’t know themselves). With the 2000 event getting the double treatment, no one born after 1900 has had to worry about those details, and most people alive right now won’t have to worry about in their lifetime either.

      Leap seconds though… we’ve had several of those and most people have no clue.

        It’s amazing that they calculated it down to that detail in the 1700s. Before that they were just a hares breath off for 1000 years (Julian calender -> Gregorian calender). It became a real issue for the church that the start of spring didn’t align with the calendar anymore, and they needed to know exactly when Easter was to be held.

        It why George Washington is credited with 2 birthdays, depends on which calender you’re going by. I think Russia was the last major country to adopt it.

        But the earth is flat and pyramids=aliens. Uh huh. Yup.

      Also when the leap years were introduced, the priests (who were to take care of the calendar) didn’t understand what dis “every four years” mean, and used to put a leap year every three years.
