Pregnancy makes you smarter

So say the might researchers as described here.

So, essentially they're saying that pregnancy enhances certain parts of the female brain, and focuses the mental capabilities on child rearing, etc.
This is like saying eating tomatoes every day will protect you from the cancer you know is coming from the 30-some cigarettes you smoke in a day.

Of course having a kid will make you smarter, because you'll sober up and realize the "withdrawal method" doesn't work, and neither does doing a handstand. You'll smarten up, because you'll have to educate yourself on how to rear a child, whether to have an abortion or not, and if you're going to keep the child, or put it up for adoption. Of course, looking at planned pregnancies... ummm. Yeah. I don't think there's actually a lot of intelligence to be gained, rather, it stresses the mental nerves to the point of breaking, and incurs a lot of issues like a syndrome similar to PTSD. It's called orneryness.
