最近听了一本书：The Longevity Project. 是追踪1500个孩童80多年的结果。
网上找到一个PDF “The Longevity Poject in a Nutshell"
要记住的就是：
It is not enough to focus on our bodies. It is equally important to focus on good social life, successful career, and healthy marriage. 具体到个人：
*有责任心（conscientiousness)
*追求事业并取得成功 （ strive and achieve career success)
*良好的社交网络（good social relations) (family, friends, community)
At its essence, individual health depends on social health.
