How hard has puberty hit you?
Hmm, that's true. But what do you know about the changes that happen during puberty?
During puberty, hormone levels increase in the body and this leads to physical, emotional and behavioral changes. For example, physical changes in boys include deepening of the voice, growth of facial hair and an increase in muscle mass, while girls experience development of breasts, and the onset of menstruation.
