Nanotechnology To Provide Immortality To Cells
Author and futurist Ray Kurzweil is sure that by 2050 anyone could have their cells repaired by nano-machines flowing through the body. Thus, the damaged and aged cells could be mended as well as organs can be re-grown and memory temporarily saved in back-up units and then transmitted back into a healed brain. Of course, the tiny robots are to be held under control not to replicate endlessly until the body rips from the inside.
