how does this even work? Why do they think it makes sense?

Kids mature faster due to diet, porn
Hey, lets have some cheetos and jerk off to Jenna Jameson.....OH SHIT! IM 40!!

This means that in some cases, boys as young as nine-and-a-half, and girls as young as eight are developing secondary sexual characteristics.
Some girls are even starting their periods before they are 10, the survey said.
"There are a few reasons why more children are experiencing the early onset of puberty," said Zeng Ke, a senior doctor at the incretion department of the Women and Children's Hospital of Guangdong Province.

He said Guangzhou's citizens have a rich diet, including nourishing soups, seafood and animal innards.
Parents also give their children supplements, such as deer antler and ginseng extracts.
These foods, Zeng said, are high in protein or essential elements and accelerate children's growth.

"Western fast foods, such as burgers and fries from McDonalds or KFC, are favored by children and can increase their development," Li Wangen, a doctor at the Second Affiliated Hospital of Guangzhou Medical College, said. [well yes, if by growth you mean massive bellies, chafe-worthy fat fucking thighs, arm balogna, and swollen spleen]

The other reason for early development is improper sex education, Zeng said. Children have easy access to books, movies or music that are pornographic.
If parents do not protect their children from exposure to pornographic material they will become sexually precocious, Zeng said.
The survey found the number of children with the onset of early puberty was less in rural areas than in the city.
