      People have kept count of things since the earliest times. We keep
      count every day. How many books do I have? How many problems
      have I done? How many goals? How many runs? How many points?
      When I was younger I worked on electronic equipment and I had to
      keep count of how many units I had repaired each day. I had a goal
      to repair more than 80 units each day. I reached 80 several times,
      but I never passed it.
      People often keep count by drawing four vertical strokes and then
      crossing them out with a fi fth stroke. Th at way it is easy to tally the
      amount at the end by counting in fi ves: 5, 10, 15, 20, 25, etc.

      Some Japanese women worked for the same electronics company
      and they kept count by writing what they said was the Japanese or
      Chinese symbol for 5.
