The evolutionary value of crying is that it calls attention to you, signaling to others that you need help. This is especially valuable in humans that (a) haven't yet developed enough to be able to articulate that they need help and (b) haven't developed enough to provide adequately for themselves, i.e. infants and young children. Crying after those ages is only evolutionary beneficial in that it potentially draws pity from others, leading them to share resources with you or otherwise help you, which of course doesn't mean much if you're a man. Note also that crying is to indicate a deviation from the norm - things are bad and they need to be made good again. The thing is with people like us is that everything is endlessly bad and there is nothing anybody can do to make things better. Not doctors, not our parents, not strangers, not the police, nobody and nothing. So the state in which a normal person would cry is our norm. And where they could be helped, like giving an infant food when he's hungry, we are totally helpless. I don't cry. I haven't cried in years and years. Sometimes I 'cry out' to God but that's it.
