Many researchers have noticed and observed evidence that children's physical development is progressing more quickly now than it had in the past. They also point to several possible causes for this phenomenon.

The primary cause seems to be unrelated to the physical child himself - it is a result of his experiences, and the fact that he is bombarded by Hollywood, television, and Internet scenes that previous generations did not have to face.

This is not to the advantage of these children. Children need time to be children, and their development should not be rushed by the media.
