How did that happen? There might actually be a Scientific breakthrough here. But, knowing us humans, I don't trust us with the possibility of knowing how to stop time in our bodies. It's not right. Poor girl.
Like Michelle said, it's a shame but I don't feel reason to pitty her. I mean, yes, it's unfortunate she'll never age and get to do all these things, but she doesn't really understand, and she is just human, but has rare conditions. It is a shame she can't live her life to the full though.
