The other day I heard that preschoolers laugh 2,000 times a day whereas adults laugh only 20 times.  Maybe this is part of the secret to youth's carefree nature.  I've begun to pay attention to myself when I laugh now.  What if we had a laughing journal?  We could post a tally of how many times a day we laughed and what were some of the reasons why.  -cjd :)
