How will such knowledge affect their lives? Do people really want to know what they will die of?

　　Many people believe that history has not always shown human decisionmaking to be bright when it comes to ethical (道德的) choices.Jeremy Rifkin is probably the most well known opponent of genetic engineering.He believes that humans are not responsible enough to experiment with genes and should not “play God”.
