Let’s be honest, many of us have forgotten a lot of the facts we learned during school. It’s definitely not something that many people want to confess to but there were just so many dates, names, formulas, and symbols that we didn’t end up having to think about or use later in life and they just kind of slipped our minds. Oops! But there are some things that we learned either in school or just throughout our lives that seem to be etched into our brains.

What do you think?
