I love this stuff. As an engineering student, I was required to take a certain number of credit hours in "arts" courses. I opted for a basic philosophy course and learned the very basics/basis of human thought. Logic problems are cool when you know the basics of philosophy. Learning the basics of human reasoning is way cool.

Of course, I used to smoke pot way back in those days, so maybe it wasn't WAY cool, but I still thing it's cool stuff.
