phalanges

How did you detect which phalanges are touched by the thumb ?

Instead people need to recal the stuff like distal phalanges.

Thus, with 12 phalanges to choose from on one hand and 5 digits to choose from on the other, we have 12 * 5 = 60 combinations.

Many civilizations used base 12, most probably because you can count 12 phalanges using your thumb.

I prefer the system where you count on your right hand's phalanges with your thumb, giving you 1-12 and use the fingers on your left for how many dozens you've counted.

I manipulate the ball itself with my pointer and two other middle fingers usually with the phalanges proximales part.

Twelve is the number of phalanges on your hand that you can touch with your thumb, so if that counting system had caught on and stuck we'd likely have a better base for divisibility.

Not correct, the frequency of multiples of 12 in human counting is thought to be because of the lunar cycle and that each human hand has 12 phalanges -- aka finger bones -- in the fingers excluding the thumb.

Inviolable control isolated to the carpals, metacarpals, and phalanges of a few... could very well be the "what we want to accomplish" which is a more worrisome truth than we can admit as a representative republic without a ranked choice ballot.
