Quote from HH the Dalai Lama

"It is much better when there is not too much seriousness" the Dalai Lama responded.  "Laughter, joking, is much better.  I met some scientists in Japan, and they explained that wholehearted laughter - not artificial laughter - is very good for your heart and your health in general" When he said "artificial laughter'  he pretended to smile and forced a chuckle.  He was maing a connections between wholehearted laughter and a warm heart which he had said was the key to happiness."  ~~~~ From The Book of Joy by H.H. The Dalai Lama and Archbisop Desmond Tutu.
