The author moved to Priya Living three years ago and began his Laughter Yoga practice soon after his arrival. Mr. Mahesh Nihalani gave the author inspiration to do something different for seniors. This book is a compilation of a number of Laughter Yoga exercises created here at Priya Living as well as based on a number of videos published on YouTube. Dr. Madan Kataria and a number of videos on the subject are shown on YouTube. They were very helpful to the author.
