To give me an idea of how many of you here may find what I'm about to tell you of practical value, let me ask you please to raise your hands: Who here is either over 65 years old or hopes to live past age 65 or has parents or grandparents who did live or have lived past 65, raise your hands please.  Okay. You are the people to whom my talk
为了让我知道这里有多少人 待会儿会觉得我告诉你的事情 有实用价值， 请符合条件的人把手举起来: 这里有谁已经超过65岁 或者想要活到65岁以后 或者有父母、祖父母的岁数 达到或超过65岁， 请举手。 好。你们就是会发现我的演讲
