It seems like the only known way to stop being a Titan Shifter at this time, is to die in one way of another. In a world filled with Titans, it kind of seems like a waste to get rid of such an ability. But maybe Hange will find a way to reverse it. Or Grisha and/or the Beast Titan already have a way to reverse it.

As for losing it, the only "old" Titan Shifters we've seen have been Rod's brother, Uri, and his father, Mr. Reiss. I guess, when you think about it, that last one anyone wants is an elderly Titan Shifter with amnesia. So maybe that's why?
