我們致力於延長人類壽命的背後，有件很諷刺的事：老年人要生活在以年輕人為導向社會，不是一件輕鬆的事。老年人會變得很孤單、缺乏重要工作、知識累積不足。此次發人深省的演講中，賈德·戴蒙帶您一同來看，在許多不同社會中對待老年人的方式，有些方式很好，有些方式則是很差，期許我們都能從經驗中獲得啟發。

當社會結構老化的同時，要如何變得更好?

The way societies treat older people ranges from abandonment in harsh environments to deep reverence in family-centered cultures. In the United States, many elderly live apart from their children and feel isolated, while traditional societies often keep elders at the heart of community life. Older people in traditional groups remain valued for their knowledge, caregiving, and leadership, especially in times of crisis. As lifespans lengthen, modern society risks wasting the talents and experience of its aging population.
