Hello, As my mind is going down memory lane I recall more than one time where my mom and I did this. When my children were little there was a childrens show on tv. I don't remember the name of the tv show. Anyway having morning coffee at the time with my mom the discussion came up on stress. We decided to give this a whirl. It does not matter how young or old we are to do this. After all we still have the little child in us all. I started out by saying Ha and than mom would say Ha Ha than I would reply Ha Ha Ha and then her turn 4 Ha's by now you know where I am going with this the next thing you know we were both laughing so hard and boy that was such a great relief to just laugh for no reason at all. I hope this works for any two or more people that would like to try it.
God Bless each and everyone of you! :)
