<span>The two enzymes p53 and Arf, were injected with a genetically engineered technique, and made the mice live longer than a normal mouse p53 is tumor supressor protien</span>
1. Arf and P53 were being injected by a technique which is engineered genetically and it is for this reason which made the mice to continue living longer.
2. People should not be engineered so as to have higher levels of two enzymes not unless the engineered is used to treat cancer.
No early death should be allowed to occur in children not unless it is God's will, therefore genetic engineering is much allowed in children.
It is good to stop cancer but it is not good to do genetic engineering to stop aging because if people they don't die there will be an increased population. In Order to reduce population if people get aged they die.
