Some of the smartest people I've noticed don't have to speak verbal douche-talk to sell you their intelligence. In fact, some of them don't have to talk at all. So many people who believe themselves to be smart, aren't. They're just loud individuals plain and simple.
Also, you know you're getting old when you're out on the city streets and you recognize the young people around you pushing strollers, feeding, burping, and cleaning up after their children. These same people are the tattooed, alternative crowd you grew up with. Not the same exact people mind you, but people comparative enough in their views and tastes that you could trust what they said as something pure; as something you could hear out of a friends mouth.
Like when these same people asked "seriously, who would want kids?!?" Now those same people are huddled together buying diapers and bibs at Target. The same scene who couldn't "afford" children are out getting "real" jobs to support their ever growing families. Am I behind on the times and immature? Does having a child make you any less of a youngster yourself? I mean, will I look my age if I'm carting around an infant? What really makes a man?
Children? I think not.
