We’ll live longer (120 years?).If the normal aging process is basically a furious, invisible contest in our cells--a contest between damage to our DNA and our cells' ability to repair that damage--then 2lst-century strides in genetic medicine may let us control and even reverse the process. But before we push scientists to do more, consider: Do we really want to live in a world where no one grows old and few children are born because the planet can hold only so many people? Where would new ideas come from? What would we do with all that extra time?

我们将活得更长（120岁？）。如果说通常的衰老过程主要是我们细胞内的一场激烈而不可见的竞赛的话（一场对我们的脱氧核糖核酸进行破坏同我们体内的细胞对被破坏的组织进行修复的竞赛），那么21世纪遗传医学的巨大成就会使我们能够控制、甚至逆转这一过程。但是在我们促使科学家再做得更多一些之前，不妨想一想：我们确实想要生活在一个没有人衰老，很少有孩子出生（因为地球只能承受那么多的人）的世界上吗？新奇的主意将从何而来？多活的那些年我们该做些什么呢？

We will live longer ,a hundred and twenty years .it is normal aging processes basically a furious invisible contest in our cells .a contest between damage to DNA and our cell’s ability to repair that damage . then in 21st century strive in genetic medicine .may let us control and even reversed the process .but before we push scientists to do more ,consider do we really want to live in the world with no one goes old and a few children are born because the planet can only hold so many people .where will new ideas come form ?what will we do all that extra time
