Hello everybody. I go by the name of Al and today in this video, I am going to talk about Longest Study on Happiness.
The Harvard Study of Adult Development also known as The Grant Study
is the longest study of adult life ever done. It's goal was to observe people for an entire lifetime in order to determine what really keeps people happy and healthy throughout life. For more than 80 years, Harvard tracked the lives of 724 men to answer the question of "What makes a good life?"
