1. #1 Hurricane-grade Sneeze The highest recorded speed of a human sneeze is 165 kph

2. #2 Beating Little Drum Your heart will beat nearly 3 billion times if you live the average life span of about 70 years. That is a lot of work for one little muscle that is roughly the size of a fist for children and two fists for adults.

3. #3 Upside Down Frown Smiling is easier than frowning. It takes 17 muscles to smile and 43 to frown.

4. #4 Dermal Deflection Skip the antibacterial soap. Your skin produces antibacterial chemicals to keep germs at bay It also produces antimicrobial peptides that protect the body from infection.

5. #5 Spit Machine Your body manufactures two to six cups of saliva each day. Over the course of an average lifetime, that is enough spit to fill two standard backyard pools.

6. #6 Breathing Room Your lungs need a lot of breathing room. The total surface area of the lungs is approximately equal to the size of a tennis court. How could that much volume be contained in such a small package? With 300 million alveoli (little cavities) in each lung.

7. #7 Tongue IDed Every person has a unique tongue print – just like their fingerprints.

8. #8 Steel Stomach Your stomach produces hydrochloric acid, a corrosive material that is strong enough to cause severe burns, and which is used as an industrial chemical reagent. This acid is necessary to digest food, and luckily the stomach lining protects the rest of the body by producing a chemical buffer as well as a mucus lining.

9. #9 Brain Power Your brain is an energy hog. Even though it comprises only 2% of your body weight, the brain gobbles up 20% of your body's energy. Your brain never takes a break – even while you sleep your brain is busy working to “replenish brain processes needed to function normally while awake.”

10. #10 Tail Wagger Humans have a tail, and some are bigger than others. In most people the tailbone, or coccyx, is composed of three to five fused vertebrae, less than a few inches long, and generally angled forward making it difficult to feel or see.

11. #11 Racing Nerves The transmission speed of nerve impulses can reach up to 402 km per hour, which comes in handy when you need to make a split-second decision or yank your hand away from a hot element, and all of this is accomplished by chemical messages travelling between neurons - in the case of decision-making or between neurons and muscle cells - in the case of movement It is also the same speed as the fastest recorded race car.

12. Your brain is all that stands between you and superhuman strength. Also known as “hysterical strength”, this phenomenon is what allows small women to lift cars in life or death situations. The brain enables the muscles to overcome their normal capacity and tap into their full potential, in part by stimulating the release of adrenaline – a powerful hormone that slows down non-essential functions like digestion and increases heart and respiration rate, thereby redirecting the body’s energy potential to the muscles. #12 Super Strength
