About This Quiz

Even more important than book smarts, street smarts, empathy or wisdom is common sense. It's not taught in schools and nobody goes professional in common sense, but it's the most important branch of knowledge in the universe. It'll help keep you dry when everything is wet and warm when everything is cold. It'll stop you from eating dirt or playing with lava. It's the reason you don't put your hand on a hot stove or park in handicap parking spots. It's the reason you don't visit the express lane with two carts full of groceries or strike up a random conversation with a person wearing headphones. It is most likely the reason you are still alive right now. 

The next time you decide to eat a bowl of soup with a spoon instead of a fork, thank your common sense training. The next time your friend hands you their phone to look at a picture and you look at one picture instead of swiping through as many as possible, thank your common sense. The next time you decide to wash your hands after using the bathroom, or cover your mouth when sneezing, or chew with your mouth closed, or decide not to rest your feet on the subway seat next to you, thank your common sense. 

If you don't have any common sense, you wouldn't have made it this far in life, but it never hurts to brush up on your skills. How much common sense do you have? Put your skills to the test and answer these common sense questions.
