Regular listeners know Erin chides me constantly about my low IQ. Or is it because her's is so high? Well, a bit of both, actually. She has an impressive 130 ('genius' is 140) and mine is a substantially below normal 82 ('average' is 90).

First of all, for those of you who say, 'You're smarter than that, you just don't test well,' thank you very much. But, sadly, it's far more than that.

When it comes to puzzle or problem solving (a big part of any IQ test) I'm really, really bad. If I don't see the answer instantaneously my brain freezes and if I continue to try to come up with the answer I become quite anxious.

That's why I'm so proud of myself for getting this one - I think. I know counting squares isn't exactly brain surgery, but the fact that I was able to focus for 30 seconds and solve the puzzle is pretty good for little old Mr. 82, me.

So take a look and do your best to count all the squares in the diagram...and, by the way, I think the answer is 11. Or at least, I hope it is. If not, it means my IQ is now down to 79.
