When I was in 7th grade, my science teacher would hand out three Smarties to each student right before a test. He claimed that eating Smarties had been shown to make you temporarily smarter, so if we got stuck on a question we could eat a few for help. We were all pretty sure he was joking, but we ate those Smarties just in case!
I'm (pretty) sure now that it was just a cute gimmick, but I still find that snacking on something while I work helps me concentrate. My biggest weakness is Jelly Belly jelly beans, so that's what I snacked on today while working on my website updates. Other days, it might be pieces of apple or pear, crackers and cheese, or cookies. (I have a major sweet tooth, if you can't tell.)
Do you like to snack on anything while you work? If so, what are your favorite snacks?
