OT- Is There a Magic Age Where Men Finally Grow Up

Of course this sentiment could also apply to women, but in this instance, let's play the men for a moment. For some reason, I have this perfect knack for attracting what seems to be perfectly normal men only to have them a month or so in turn into player BEASTS! Are some men players for life? Is there an age where that part is finally over and I should make that my new target? I'm telling you, immobile 70 somethings are looking pretty damn good to me right now. Provided of course they'll let me borrow their old man handicap parking tag and senior citizens discount.
