We learn in school that we have five senses: eyesight, hearing, touch, smell, and taste. What we call the "sixth sense" is quite misnumbered, as there are plenty of other senses that are just too hard to explain to kids in school.
Vox looks at some the other senses we have, such as the sense of knowing where our body parts, temperature perception, and a sense of balance. We only become aware of these other senses when something goes wrong with them. They don't speak of common sense or Spidey sense or a sense of humor. -via Laughing Squid
