Background InformationThe fast development of biotechnology has brought in more options for people to improve their lives. One of the scientific achievements of biotechnology is that people may have access to their genetic information. If we’re going to use genetic knowledge, should we use it to improve ourselves? Do you want to make better babies? Do you want to make taller people? Faster people? Stronger people? People with better memory? That’s not going to happen right away, but it will. This revolution in front of us is as personal as it gets, concerning our gender, our race, our family. But how much do you really want to know about your future health? One of the great ironies of the genetic revolution is that it teaches us about our flaws, our limits. We now know that’s what’s going to hurt and that’s what you are at risk of.
