The possible facial expressions in combination is 43(!), also known as 43 factorial, meaning there are 60415263063373835637355132068513997507264512000000000 possible combinations.
Another way to look at that is, 6.0415263e+52, which is also just over 6 Sexdecillion, or in newspeak, six times sixteen-illion.
There are 6, 16-illion, ways for you to start a sentence.
It sorta makes you feel bad for people who never say anything new.
Then multiply that by itself everytime there's a word in the sentence and the number quickly exceeds more than there are stars in the sky.
Fate changes paradoxically, so multiply the number by infinity and divide by zero until everything echoes as reflections thruout the universe.
We could describe every point in existence to increase the chance of discovering something that works, instead of agreeing on how to repeat, or repeating how to agree, on what's broken.
