I agree, I say so often that people depend so much on things in life that they don't know the first thing about.

But then again, it's that the point of our educational system, to teach us these things? One month of basic auto repair in high school is more useful to more people than trig.

I work with people, many of them lawyers or para-professionals, who don't know much about the cars they drive to work, the computers on their desk, the boiler in their home, etc. ... and it bothers them! Luckily, they can all pay someone else to take care of these things for them, but there are others who are just as in-the-dark but can't as easily afford it.

I think it's a failing of our education system.
