As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at 31 . Its cells would grow old fast and it would die young. 32 until the technique is perfectly safe, it should be 33 .
I'd love to have a clone of 34 . I often wish I had a twin sister, someone who 35 me in everything. So why not a clone? Well, the idea 36 be fun but I'm not sure if it would be 37 . I think we would be playing with fire if we let scientists go ahead with 38 cloning. There are so many 39
