Two comments: In change bell ringing, the towers where I ring have 10 bells, and in place notation they are:
1, 2, 3, 4, 5, 6, 7, 8, 9, 0. Some towers, such as in New York, have 12 bells, and they are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, E, T. Counting using digits: Yes, if we used sandals, we could do base 20; half the population perhaps could use base 21.
