I did a presentation yesterday on NFAL and my laughter count went way up! I even had several participants say they wanted to count the number of times they laugh each day. So far my best day (yesterday) was about 20. I am getting into shape.
Laughter, according to Dr. Sethi of the U of A does the following:
It dissolves distressing emotions, if only momentarily
It relaxes, recharges and energizes
It shifts perspectives--enabling you to see things from another viewpoint making things less threatening
Check this out for the laugh of the day
