There's no proof that she's going to live any longer than a normal human. She's just developing much more slowly than normal. She's also had many severe medical conditions which required intensive medical care. She still has to be fed via a gastric feeding tube. I doubt anyone with a similar condition would have survived the first 5 years of their life as short as 60 years ago.
