Which is the result of a genetic defect, I fail to see how reversing age and regenerating optic nerves means the particles can flat out rewrite DNA. No to mention that the federation would consider that illegal, what with the whole ban on genetic engineering. assuming that this isn't also the result of a genetic defect. We don't really know what causes Bendii Syndrome, so its a bit presumptuous to claim what might be able to cure it. And yet there is no evidence in any Star Trek production that the particles are being used by the federation, no looks any younger and people still die from stuff they're allegedly supposed to prevent death from. Most importantly Picard and his crew haven't been court martialed and are still on the Enterprise except Worf who got an ambassadorial job to a major federation ally, in fact later Riker was getting his own command. The other reason I doubt it is that the guys writing it who made Dougherty and the Son'a the bad guys WERE STILL RUNNING THE FRANCHISE. So they are going to go back on what they wrote why exactly? Because given past history fans complaining on the internet doesn't do crap.
