An Even Five

I am convinced that the number 5 is even.

Not mathematically even, mind you, but conceptually even because humans have 5 fingers per hand , thus a "whole hand" is an even value.

If you want proof, think of it like this:
  • The number 4 is indisputably even. 
  • So is the number 6. 
  • But 7 is indisputably odd. 
  • So if you are given the sequence 4, 5, 6, 7 and told to eliminate the number which doesn't belong (or doesn't "feel right"), which one do you cross out?

You could pick "5, 6, 7" and not be wrong (because there's no wrong answer to this), but I'd wager that most people will pick "4, 5, 6" . This is because 5 both "feels" even and is right in the middle where it "ought" to be (because 5 is half -- right in the middle -- of Base 10). "4, 5, 6" just feels like a string of three even numbers that other sequences don't give.

Five is the "even" number that belongs in the middle. (Or at the end, which is why we love counting in units of five. Again, Half of Base 10.)
