I agree that governments may be blocking the development of the genetic
research and the reason is simple - to prevent overpopulation. On the
other hand it seems rather impossible to block the research in the
whole world. Another thing is whether or not extraterrestrial beings
have given us information in detail on genetic codes and techniques
stopping ageing. Maybe they have but the truth will be difficult to
detect, or maybe they have not as perhaps they do not much care about
our civilisation, mainly doing their own research in the Earth.
