You never know, I was talking to my 12 year old cousin just a week ago.

She wasn't very interested in Twilight, however, she kept constantly asking me questions about string theory, black holes and quantum physics.
I was so proud! She is definitely a future slashdotter.

I'm sorry, but scientifically that makes no sense. You die mainly because of cell damage accumulation (although there are other factors involved). Even if her mutation is making her somehow age slower, it doesn't mean that her cells will magically accumulate less damage.

Ah, the Human way of finding life:

Astronaut 1: "So, any signs of life?"

Astronaut 2: *shooting a flamethrower at the ground* "None."

Astronaut 1: "Ok, just to be sure let's blow everything up and scan the debris."

Scientists are baffled by the realization that most things that matter are either Good - Or Bad.
