Teenagers! It's all about the teenager. Not that its a dream run either side of the hormone rush.

Purely observational as a boy parent, society at large welcomes boys in all their glory. Young women are put in more constrained boxes more of the time. Bad boy behaviour is more likely to be excused or only mildly punished, bad girl behaviour is the "reefer madness" story for drugs, booze, sex, violence and body dysmorphia.

I find it easy to believe this study. Not welcome news btw or even welcome "olds"
