The potential power of predictive genetic testing as a risk regulator is impressive. By identifying asymptomatic individuals who are at risk of becoming ill, predictive genetic testing may enable those individuals to take prophylactic measures. As new therapies become available, the usefulness of genetic testing undoubtedly will increase. Further, when a person's family medical history indicates a propensity towards a particular genetic disease, a negative test result may open up otherwise denied opportunities by showing that this person has not inherited (...) suspect genes. In the latter type of case, a negative test result may reassure the individual that pursuing a particular course of action is worthwhile, or may convince prospective employers that the individual will be a serviceable employee.

Slowing the aging process would be one of the most dramatic and momentous ways of enhancing human beings. It is also one that mainstream science is on the brink of pursuing. The state of the science, together with its possible impact, make it an important example for how to think about research into all enhancement technologies.
