I found the episode pretty good and the whole thing with the guy who give immortality make us wonder if life its not better when we know that we will have an end of it and that make life exciting and that make life pretty unique and pretty rare . And i enjoyed also to see the guy who when he become immortal , life seem tasteless and empty of meaning and i really love that kind of lesson and make us remember that life is pretty precious and limited . So i found the episode pretty good and really enjoyed it the lesson behind the episode . Very nice.
