We already do that to some extent. As far as current prevailing theories go, our bodies are nearly entirely replaced every few decades by cell death and regeneration excluding certain cells in the brain.

This part in particular:
"About the only pieces of the body that last a lifetime, on present evidence, seem to be the neurons of the cerebral cortex, the inner lens cells of the eye and perhaps the muscle cells of the heart. The inner lens cells form in the embryo and then lapse into such inertness for the rest of their owner's lifetime that they dispense altogether with their nucleus and other cellular organelles.
But if the body remains so perpetually youthful and vigorous, and so eminently capable of renewing its tissues, why doesn't the regeneration continue forever?
Some experts believe the root cause is that the DNA accumulates mutations and its information is gradually degraded. Others blame the DNA of the mitochondria, which lack the repair mechanisms available for the chromosomes. A third theory is that the stem cells that are the source of new cells in each tissue eventually grow feeble with age."
If this all turns out to be true, then a method for improving the transcription and translation processes during cell division should be found if we want to find immortality through a biological means. On the other hand, a mechanized version of humanity would seemingly be considerably simpler. Considering that we already have various means of interacting with the brain in the form of prosthetics, this may not be as complicated as it seems. Given that the neurons that comprise who we essentially are seem to be permanent, immortality could be considerably closer than people seem to think.
Sorry for the rather long drawn out post. I'm just really interested in this stuff.
Is it normal I thought of a way to live forever?
