Is “Baby Brain” a Myth?
Scientific American: As many as four out of every five pregnant women say that they suffer from “pregnancy brain”—deficits in memory and cognitive ability that arise during pregnancy, making women more forgetful and slow-witted.

The Wall Street Journal: When Richard Laermer walked into an eyeglass store in Paris, he was surprised to find fewer than 10 frames for sale, each displayed on top of its own large pedestal.
