The decimal system should have been the dozenal system but good luck getting people to switch from decimal to dozenal.

I don't know how many fingers you have, but decimal system makes more sense to me...

You can count to twelve on your hands just as easily. And that’s per hand. Numberphile explains: https://youtu.be/U6xJfP7-HCc?t=500

Since childhood, I have always counted 16 on 4 fingers. Top of finger tip as 1, then the dark lines between knuckles, on inside side of finger as 2,3,4. After 16, I continue with 17 on first finger again, but left hand has now 1 touched by my thumb. Technically its 16x16 numbers.

Since I lost 4 in the accident, I have 12 left.

Because you get paid in coins and have to divide them in 2, 3, 4, 6'z?

*but i do now understand the use of a thru'ppenny bit.
