Enhancement and ethics

Now suppose we could use genetic engineering, regenerative medicine or drugs --chemical enhancers, or reproductive technology or nanotechnology to produce healthier, fitter and more intelligent individuals, what should our reaction be? Would it be unethical to do so? Would it be ethical not to do so? Our question is this: If the goal of enhanced intelligence, increased powers and capacities and better health is something that we might strive to produce through education, including of course the more general health education of the community; why should we not produce these goals, if we can do so safely, through enhancement technologies or procedures? If these are legitimate aims of education could they be illegitimate as the aims of medical or life science, as opposed to educational science?
