Why is it so hard to catch even glaring errors? That’s one of the questions addressed in “Your Bleeped Up Brain.” Viewer John Chismar sent me this picture of a shop near his home. He writes, “Your program reminded me of a photo I took a few years ago of a printing shop around the corner from my house. I took the photo a few days after they beefed up the store’s appearance. To be honest, I never noticed anything was wrong until a visiting friend pointed out the error.” Thanks, John!
