So today after work, my coworkers battery died, and he asked me if I could help him start his car. While he was doing it, I realized I don't even know how to do it even though I saw a video on it few years ago (25m) I kinda got depressed that I don't know simple stuff like how to check the air pressure or change the oil. Where do people learn this stuff from? I spent my youth kinda depressed living a with an alcoholic father, maybe thats the reason I don't know many useful skills like that.

I was wondering besides changing the tire, changing oil, jumpstarting a car, what other skills are there that are a must for men.
