Why do girls live a much easier life than boys?

I am a girl, and I would have to disagree with this! Boys "choose" their life style, they make their lives difficult. Girls go through their period phase... every month for 3-5 days, yes boys go through pubirty ONCE.Girls birth and take care of children, while boys can just relax and enjoy their life.. The one who is always expected to b there is the girl. Now what about a girls life seems so easy?
