I watched this Ted talk today. Robert said about Harvard study on many people life. The study conduct for over 70 years on many people in many variety of status from poor boy in Boston, a man from wealthy family or normal person doing his routine job.
The result of the study is really interesting. It shows that the most important thing of human to live longer with happiness are the quality of relationship they have. The poor relationship tend to shorten people life. The good quality of relationship make people live longer.
The study explain in science that the quality of life reflect the performance of the brain as well. The loneliness person will have shorten life and the brain underperform and lose its capacity. On the other hand, the person live an enjoyable relationship make more long live and healthy brain.
In the conclusion, He asked about what about you. What we are searching for is it wealth or famousness or happiness.
