.... livers and lungs and things like that? The heart is just a pump, big deal, how hard can that be? The liver is just a filter ..... Fram, if they were smart would be all over this Lungs, that little deal a little more complicated but it could be done. They have iron lungs, so why not make lighter carbon fiber lungs that could perform double duty as a shield from bullets and stuff like that while they transfer the O2 to your body? It seems like we have all this high tech brain power going on these days, but the product is for useless entertainment / face time and nothing else. Are there any really cool medical breakthroughs anymore or are all the Doctors just spinning their wheels on the Ferrari or Golf forums?
