They 2.are not longer children, but are not yet adults either. 3.A once loving and obedient child can transform into a rebellious, sullen teen. What accounts for this 4.change? The problem, claim some doctors, lie in the physical aspect of the person. A teenager's 5.hormones wreak havoc within their body.
