Agreed. Grad School too, none of these teach you anything they just take your money in exchange for a piece of paper that may or may not be worth anything. But, I found most of my knowledge has come after school (about 25+ years ago for me). I have been thinking lately that your single status may contribute to intelligence.

Friends who are married or have kids simply don't have time to learn anything. They work all day, get home and make dinner for the family, eat, maybe if they are lucky get to watch some show they didn't pick and then go to bed. On the weekends they typically do events to keep the kids happy. Same with men but they generally have slightly more free time.

While I have the 2 hours or so after work to look things up on the internet or watch a new documentary on Netflix etc.

I often see age discrimination at work because it is believed (and sometimes true) that the older you are the less you want to learn anything new. Well I see this different.. it isn't about being old.. it is about being old and having spent your life not learning. You have spent 20+ years not learning (taking care of the kids) and so of course it is hard for you and you don't want to do it.

While because I am single I have the time and desire to look at things and investigate things and I have been learning my entire life.

That might be the common denominator when I see people that are checked out... they are too busy to think critically. I couldn't live like that.
