I'm 22 and I've told older guys before (who are married) that I don't think I necessarily have to get married. If I find the right person that's great, if not no big deal. I've gotten various responses but one that stood out was that single guys dye younger. Is this true? Or are they pulling these stats out of their asses? And if it's true what's the reason behind it and what can be done it about it?
