    We'll find the answer to the genetic code（遺傳密碼）．

    Scientists will learn more about the genetic code and how our bodies work．Many serious illness will be less dangerous because there will be a cure（療法）．

    We'll live longer．

    People will live longer because people won't get serious illness．New medicine will keep us strong and healthy．Maybe we will live to be 120 years old，but what shall we do with such a long time?
