What is the reason for all the movement when we really need to go pee? Is it a subconscious reaction to distract the mind from a full bladder, or does sloshing the pee around in your bladder make it somehow better? I would assume not, since that probably increases the physical urge that you need to go pee, but why then do we dance and hop…
You can actually test this pretty easily!
Have you ever walked out of a dim building into sunlight so bright it hurts? Well, each eye has a max limit of how much it can hurt, but your brain combines the pain from both eyes.
If you close one eye, you cut the pain signal in half.
