"P. S. R. Parallel Synchronized Randomness.
An interesting brain rarity and our subject for today.
Two people walk in opposite directions at the same time and then they make the same decision at the same time.
Then they correct it, and then they correct it, and then they correct it, and then they correct it, and then they correct it.
Basically, in a mathematical world these two little guys will stay looped for the end of time.
The brain is the most complex thing in the universe and it's right behind the nose."
