Doctors think her body is out of sinc, meaning its not working together, like ours, but its working seperetly, she hasn't gone threw puberty, she has looked the same since she was 2, and her brain has not grown at all. Its really weird, they're trying to find out the gene and test it on rats and see if it slows down the aging in rats, if it does, she could possibly hold the key to ageing.
Its a sad story, but it might hold the answers to some things. Remember, every one on this planet is here for a reason .
