You see, I'm a *mature* crazy person
The secret which Joss and Tim were "laying in" to develop it later.
I think i know what it is.
Clues:
- syringe (pointed out by Joss)
- "Don't wanna die at all" (pointed out by Tim)
- "You look excatly like the day I left" (pointed out by me humble self, yay!)
So, obviously, she uses some injections to stay youthful.
The question left is this: is she as young as we think she is, or is she, like, 80 y.o. already?

Тоже вариант. Doesn't explain the third clue though, so i stand by my theory
Мне кажется, тут какая-то смертельная болезнь
По-моему, в сериале она позиционируется именно как дэвушка зрелая и вся такая духовно просветленная
дэвушка зрелая - мож быть. Но судя по поведению с Мэлом мозга у неё не наблюдается. А уж истерика после обнаружения, что Мэл спал с Нэнди, - чисто подростковая.
