9

Here's something interesting I learned from the Human Calculator.

Take your age, add the digits, and subtract that number from your age.

The resulting digits will add up to nine.

Example: I'm 38. 3 + 8 = 11. 38 - 11 = 27. 2 + 7 = 9.

Now I know what the Beatles were droning on about.

Number nine. Number nine. Number nine. I'm really scared, too, because when I played hockey, I always chose the number nine.
