nope:P
Well it's true Pure Quin, exercising the mind requires thinking. If it wasn't for Thingfish's riddle I would not be taking things alot more seriously than I do with word games etc now.
My mind was once quite blind to literal meanings and different sides to different stories etc, but now, as you can see, and even if you looked in the MORE RIDDLES! thread in FF7 you'd be able to see that I have a wider range of viewing now.
Challenging the mind is the best thing you could do. It makes you more aware and smarter at the same time. If you are ignorant to complexity then you will always remain ignorant unless you make an effort to look beyond the lines.
That's the only way you'll ever be able to understand a wider range of knowledge than you already know.
