Maturity and US training augur well for Wilson as she eyes record performance
The gawky adolescent who sat on her mother's lap is no more. Hannah Wilson has blossomed into an independent and self-assured teenager.
The 19-year-old Wilson firmly believes this maturity will hold her in good stead when she mounts the starting blocks at the Water Cube in her pet event - the 100 metres freestyle.
'I have grown a lot in the past four years. I'm not a little 15-year-old any more,' said Wilson. 'I now know what to expect.'
She is not talking about her physical well-being, but rather mental maturity.
Four years ago, on the eve of her first Games in Athens, she sat awkwardly in mum Jane's embrace for an interview during her lunch break at Island School.
School is out now, and the timidity has been replaced by poise and confidence.
