You Have More Than Five Senses

Researchers have estimated that humans have anywhere between 9 and 21 total senses. Some, such as pressure, itch, and pain, might seem like they should be included under the umbrella of touch, but have their own receptor systems. Thirst and hunger can also be considered senses. Even our sense of time may count as a separate sense, and it seems to be more honed when we're younger.
