1) Explain why increasing the amounts of the two enzymes changed the life spans of the mice.

2) Express your opinion about whether people should be engineered to have high levels of the two enzymes. Should people have the option to do this if they would like? Should parents be allowed to have it done to their children? Is it okay to do it to stop cancer but not okay to do it to stop aging?
