It's the opposite of a nanofactory.

You're ignoring that regardless of gender at that age you are growing and increasing strength. The comment I made above was a partial copy / paste from my former coach who is an extremely experienced and had at least one athlete in the Olympic trials this year. He has also been participating in exchange programs with Chinese coaches over the past year. Pretty sure he knows exactly what he's talking about vs commentators and pundits who know near nothing about the sport. It's all sour grapes at being beat by a Chinese girl.

Yes, there is past history (distant) in China, but there is nothing to suggest she or any of the other Chinese swimmers are cheating. She passed all her tests so far this year. In fact, she has NEVER failed a drug test and has been tested often in the past several years. People, 16 year old swimmers can do some amazing things. But what did she really do? and was it all that amazing? She dropped from a 4:33.6 to a 4:28.1 in the 400 IM. a 5.5 seconds drop (a 2% improvement). In the 200 IM she dropped from a 2:09 to a 2:07 (a 1.5% gain). People are saying that that is not possible? REALLY? When Michael Phelps was her age, he dropped 7 seconds in the 400 IM (from 4:22 to 2:15 - or 2.6% gain) and 2.5 seconds (from 2:03.4 to 2:00.8 - or 2% in the 200 IM from age 15 to age 16. Basically, the same statistical improvement, or even a little more. No one even suggested his gains were anything other then natural.

It was. You may remember a film called Fern Gully: The Last Rainforest. http://www.imdb.com/title/tt0104254/ Ok early 90's, but still....
