The first one I'm going to talk about is how to get from a relatively modest amount of life extension -- which I'm going to define as 30 years, applied to people who are already in middle-age when you start -- to a point which can genuinely be called defeating aging.
第一个步骤是 如何从一个相对适中的延长寿命治疗科技 - 我这就把它定义为可延长三十年寿命， 并且在已经是中年年龄的人开始应用 – 直到一个能真正被称为战胜老化问题的程度。
