Ditching your memories, huh? That's actually a good idea. Experience shit for the first time all over again, like the boring crap that would drive you nuts if repeated ad infinitum. I mean, I'd want to keep certain stuff like remembering how to be awesome at fighting, but immortality wouldn't be too bad if, like, every door you opened didn't remind you of every door you've ever opened every day for hundreds of years to the point where they all blur into one monotonous door that laughs at you because you can't kill yourself.
