Second, might it be possible to clone one's self, and transfer one's brain's memory lobes to the new him or her, and essentially continue living through the cloned version? By transferring merely the memory lobes as opposed to the brainstem, paralysis conceivably wouldn't result. I've read in the past that memories can be transferred in this way, and since it's one's clone then I guess the risk of tissue rejection is greatly minimized. This all sounds feasible then, right? If so then I bet whichever biotech firm offers it (from a country where it can be offered) will make a bundle with the aging baby-boomers of the USA and Europe (etcetera). Folks not only seek immortality, they seek renewed youth.

Now let's up the ante a bit... Can the new version of one's self be genetically improved but STILL accept one's brain's memory lobe tissues withOUT organ rejection's likely occurrence? Or would even that slight genetic modification (to make one smarter, or more phyiscally "ideal", or whatever) greatly increase the risk of tissue rejection from the original donor human?
