That sounds very sci-fi!!! Not sure I like it. Jeez what happened to just getting old and passing away. But hey, if I had two bodies then I can redesign the new one with new tattoos
I'm quite comfortable with the idea of getting old, because I'm already more than half-way there, and I truly see no virtue in prolonging life any more than is necessary.
The brutal truth about all these ideas to stave off the ageing process or produce children who are free of disease, is that people are already living longer, thanks to medical discoveries, but the world is seriously over-populated. If this situation is allowed to continue, life on Earth will eventually be totally unsustainable because we would run out of food, and probably drinking water, and, as a result, die from starvation anyway.
