The base 12 I got. I just can't visualise how you keep your place.

I curl the fingers on my left hand for the digits 1 to 5. And if I curl 
the fingers on my right hand, in a binary fashion, for 5, 10, 15, 20... 
up to 155. So I can count up to 160 or in the range -80 to +80.
(I have had some boring jobs in my life.)

I am trying to reverse the opinion that counting on your fingers is a 
sign of being poorly educated. So I am always on the lookout for 
different ways to do it.
