I always think
that life would be much more sensible had humans evolved with six fingers on each hand. Then we'd have used a base twelve counting system.

12 is a far nicer number than 10 (although in base twelve the number we call twelve would be represented as 10, if you get my drift) as it's divisible by 1, 2, 3, 4 and 6, whereas the latter is only divisible by 1, 2 and 5.

The base twelve metric system would have been inherently useful as well as numerically simple and we'd have used it automatically.
