Peters correct about the sample size! I mean Dolly is about 6 years old and her mother died aged 3 didn't she? But that doesn't mean that cloning doubles a lifespan.

Right now its embryos and babies, but what about cloning adults? Would an adult clone have to grow for 20 years or so?

Is it possible then to go onto the next step (in theory) to clone memories and personality and implant them into a new host? Say you lost your legs in a car crash... could they clone a new you of the same age with all your memories? In theory? I've heard of genetic memory, but this may not be the same thing.

Will us humans be immortal?
