We're always told to dress warm for the winter lest we catch a cold. But despite the name, cold weather has nothing to do with the virus we call the common cold. Cold weather causes us to stay indoors more, and the enclosed setting increases the chances of coming into contact with an infection. Basically its people that make us sick, not the weather.
This irritating misconception remains ingrained in popular culture to this very day, as referenced in films such as Lucy, Limitless, and Inception. But we do use 100% of our brain throughout every day of our lives; its just that certain areas are used for specific functions at any given time. When you think about it, it wouldn't make much sense for 90% of our brain to be useless meat.
