people this is coming from a person who has been a transfan since late 1983 when the whole thing started as a toyline. this is just a theory that i have had over the past couple years. when it comes to nano technology in general and its overall reinventability and everincreasing complexity and for lack of a better word sopistication i believe that it may yet one day reach such a stage in its existance that it would eventually exist on a submoleculer level in a nannite like state of being. in short it is quite possible that when it eventually reaches that point that a way could be found for a person to use it in the form of a full mind body celluler submersal. that is to say that the person in question could use it on his mind and body on a submolecluer level quite possibly with it at most enhancing his bodies natural healing capabilities to the point of extreme celluler regeneration. a good example of said advanced regenerative healing could be seen in the xmen character wolverine for example. now imagine that the nanite technology does that in addition to it performing constant day to day maintenance to that persons body on a submoleculer level with it basicly maintaining that persons body to the point that the person is entirely capable of living his life in what could only be described as a self perpetuating prime state of existance while that person is kept at the absalute peak of his youth. in short it prolonging his life span over time in a indefinite manner. in some part with time it would achieveall of that in addition to it rewritting that persons genetic code so as to remove any and all genetic flaws and otherwise inperfections. over time with it repairing and or outright replacing the various parts of the human body with a technological counterpart over an incredibly gradual period of time until eventually the persons body has taken on an entirely technological state of being and thus renderign that person thoroughly immune to any and all natural viruses and diseases in short people one of us becoming one of them like i said people this is just a theory i have put together over the years and yeah i probably have read way too many sci fi novels although i do believe that the very idea stated in this theory does have merit and may yet in some part be made a reality one day.
