We were about to leave the supermarket when we were stopped by someone conducting a survey. He showed me a piece of paper with connect-the-dot images for a cartoon wedge of cheese, broccoli, and a carrot. Underneath each image was a label with scrambled letters. And beneath that were a few basic questions about vegetables that we had to answer in pencil. Somehow I kept starting with the wrong letter and misspelling everything. I suspected it this was a part of the experimental design. The experience made me feel old.
