Nanotechnology will help resolving a whole bunch of problems, but might I
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?
