1. The longest recorded bout of hiccups lasted 65 years. That’s not a bout, it’s a lifetime!

2. In the course of a lifetime you’ll produce enough spit to fill a swimming pool.

3. The average person will spend 6 months of their lives on the toilet.

4. The liver is the largest gland and the second-largest organ in the human body. 

5. The aorta is the largest artery in the human body. Its diameter is about the same as a garden hose.

6. The only jointless bone in the human body is the hyoid bone in the throat.

7. Don't stick out your tongue if you want to hide your identity. Similar to fingerprints, everyone also has a unique tongue print!

8. Your pet isn't the only one in the house with a shedding problem. Humans shed about 600,000 particles of skin every hour. That works out to about 1.5 pounds each year, so the average person will lose around 105 pounds of skin by age 70.

9. The small intestine is about four times as long as the average adult is tall. If it weren't looped back and forth upon itself, its length of 18 to 23 feet wouldn't fit into the abdominal cavity, making things rather messy.

10. The source of smelly feet, like smelly armpits, is sweat. And people sweat buckets from their feet. A pair of feet has 500,000 sweat glands and can produce more than a pint of sweat a day.

11. Blood has a long road to travel: Laid end to end, there are about 60,000 miles of blood vessels in the human body. And the hard-working heart pumps about 2,000 gallons of blood through those vessels every day.

12. Blondes may or may not have more fun, but they definitely have more hair. Hair color helps determine how dense the hair on your head is, and blondes (only natural ones, of course), top the list. The average human head has 100,000 hair follicles, each of which is capable of producing 20 individual hairs during a person's lifetime. Blondes average 146,000 follicles. People with black hair tend to have about 110,000 follicles, while those with brown hair are right on target with 100,000 follicles. Redheads have the least dense hair, averaging about 86,000 follicles.

13. No wonder babies have such a hard time holding up their heads: The human head is one-quarter of our total length at birth but only one-eighth of our total length by the time we reach adulthood.

14. If you say that you're dying to get a good night's sleep, you could mean that literally. You can go without eating for weeks without succumbing, but eleven days is tops for going without sleep. After eleven days, you'll be asleep-forever!

15. The acid in your stomach is strong enough to dissolve razorblades. While you certainly shouldn’t test the fortitude of your stomach by eating a razorblade or  any other metal object for that matter, the acids that digest the food you eat aren’t to be taken lightly. Hydrochloric acid, the type found in your stomach, is not only good at dissolving the pizza you had for dinner but can also eat through many types of metal.
