Eh, the royals live a very long time. Her mother made it to 101 years old. There's probably something to be said for being very, obscenely rich and not working a day in your life I guess.

Also I don't want her to die. The press coverage would be fucking nauseating, and it'd drag on for years.

The only way I'd want her to go is if she dies doing something public and obscene so the press has to do their best to downplay it.
