Another Useless Fact in Life After 60

The stuff they tried to teach me in high school like Algebra, Biology, History, and such at the time was filed under the category of “useless facts.” I didn’t know what I was going to be when I grew up but whatever the choice I wouldn’t need those subjects.
So on that note, I present to you a few useless facts.

1. Turtles breathe through their butts! (I have been around a few humans I think did the same)

2. The King of Hearts is the only king in a deck of cards without a mustache. He is also know as the suicide king.

3. Dreamt is the only word in the English language that ends with “mt.”

4. The opposite sides of a die will always add up to seven.

5. Those metal studs on your jeans have a name and a purpose. Rivets, as they’re called by Levi Strauss, are placed on certain spots to add extra support where the denim is more likely to wear out and rip. (This can’t really be true or the seat of them would be filled with.....Rivets)

6. No number from 1 to 999 includes the letter “a” in its word form.

7. The average adult spends more time on the toilet than they do exercising.

And there you have it…useless facts that are, well useless, until you find yourself a contestant on Jeopardy.
