Contemplating reality is exhausting. I mean, when you ponder on Einstein's theory of relativity and how everything you perceive that creates your reality depends entirely on the circumstances you're viewing it from, don't you just want to curl up in a little ball of existential dread and roll yourself into the woods, maybe while screaming?
We sure do. But the better option might be simply to distract yourself with some other things that are still cool to ponder, but don't contain the terror of reality.
