Lowe is actually only 28 and has had 2 children!
She took 2007 off to have her first child, and then took last year off to have her second.
In addition, she was doing her masters degree this year, I don't know where she got the time. It's just unfortunate for fans that her pregnancy's left her with little more than a few months to get in competition shape before the olympics. In 2010, she was at her strongest, World leader in the high jump, US long jump silver......Perhaps she'll come back to the sport in 2014/2015, but what might have been if she had have committed full time to the sport.
Kudos to her for doing so well when the HJ was essentially her hobby!
