if you count in binary then you can actually get to 31 with one hand instead of 10
comments
if you include half closed fingers as a third state and use your wrist as a "6th finger" you can go to 729 on one hand or 531441 on both.
we do not speak of ternary logic, binary is king
pretty sure you can count to 1024 if you used all of your fingers and thumbs
1023, actually, but yeah
Interesting
