Nanotech is an area I try to keep up to speed on especially when it concerns space or medical applications. Howard Lovy writes an article Wired that showcases how medical nanobots might one day fight diseases such as cancer. Personally my attitude is that if I can keep myself healthy long enough I might benefit from some of these future technologies which could extend my life.
