"If we combine the benefits of a human physiology maintained at the level of effectiveness possessed by our bodies when we were children (e.g., dechronification), along with the ability to deal with almost any form of severe trauma (via nanosurgery), then there are very few diseases or conditions that cannot be cured using nanomedicine. The only major class of incurable illness which nanorobots can’t handle is the case of brain damage in which portions of your brain have been physically destroyed. This condition might not be reversible if unique information has been irrevocably lost (say, because you neglected to make a backup copy of this information). There are several other minor “incurable” conditions, but all of these similarly relate to the loss of unique information."
