However old you are, you're retarded, and by that I mean very very dumb.
I'm sure Tuohy can do math, and I'm sure she knows 9:47, while great, is not better than 9:05 for 3K or 15:37 for 5K. By better I mean superior.
Even if she can't do math, someone in her orbit probably can. By orbit I mean people around her.
Also, she probably makes an effort to come off as humble in interviews, given that she is obviously acutely aware of her own reputation. By "her reputation" I mean that people see her as one of a kind.
