Interesting thoughts come to mind with counting. I count out Rhythms when walking or smoking. Not an actual number, but each movement sounded out in measured meter maybe? 4's or fives, not sure but the movements would be paced out and unconciuosly counted and kept a pace. Not all the time.
Then again, I knit every chance I get. Lot's of numbers in knitting, so I am constantly counting under my breath when knitting. But Is it just part of the hobby? I find that many hobbiest's crafters are a bit OCD like, especially the big O.
