> One word: Nanotechnology

Nanotechnology will help resolving a whole bunch of problems, but might I suggest that we do not think of it as a magical artifact capable of fulfilling all our dreams?
I do not think that nanotech alone would be able to solve the problems of cell death and brain malfunction. Nanotech could not produce new veins or blood cells nor would it be able to rejuvenate the old body cells. Cells divide, and in the aging process, this becomes more and more slowly until it eventually stops. How would Nanotech be able to alter this?
