"More than 250 years ago, the philosopher Auguste Comte suggested that "Demography is Destiny". It is this change in demography that is leading toward that destiny: nothing less than a transformation of medicine and our collective relationship with it. From advances in composite tissue transplantation to stem cells to bionic human-machine interfaces, we are experiencing a present-day revolution in replacement parts. As these advances merge with similar progress in consumer and medical devices, the aging individual will be forced to ask the question: What of us will remain innately "us"?" - UA College of Science
