Question 1 of 20 Correct

What does an appendix do?

Correct! Sorry, that’s incorrect.

The correct answer is: The appendix, a tube-shaped organ that rests near the junction of the large and small intestine, has virtually no function. You can live a completely normal, healthy life without it. It's believed the appendix had a more important role at some point, but our bodies have evolved and no longer need it.

Question 3 of 20 Correct

True or false: You cannot tickle yourself.

Correct! Sorry, that’s incorrect.

The correct answer is: This is true. Go ahead--try it. You can't tickle yourself. The area of the brain responsible for movement can predict a tickle. It alerts the rest of your brain that the tickle is imminent, so the pressure and feelings you'd normally experience during a tickle aren't experienced.

Question 5 of 20 Correct

True or false: Men experience menopause, too.

Correct! Sorry, that’s incorrect.

The correct answer is: This is true. However, the condition is like female menopause in name only. As men age, they may experience a decline in testosterone. This dip in the hormone can cause fatigue and depression—as well as sexual side effects like a lower libido. But the change is much slower, much less severe and some men never know it's happening.

Question 6 of 20 Correct

What is the function of the gallbladder?

Correct! Sorry, that’s incorrect.

The correct answer is: The gallbladder, a small sac located just under the liver, releases bile, which helps digest the fat in food. But much like they can live without their appendix, people can lead normal, healthy lives without their gallbladder.

At what age do babies form their first memories?

Weird Body Facts
Question 9 of 20 Correct

True or false: Bones are stronger than steel.

Correct! Sorry, that’s incorrect.

The correct answer is: This is true. Pound for pound, bones are stronger than steel. Bones are amazing--they are light enough to bend, twist and turn with our bodies, but they're also capable of holding a great deal of weight and stress, too.

Weird Body Facts
Question 10 of 20 Correct

How many kinds of tears do humans have?

Correct! Sorry, that’s incorrect.

The correct answer is: Humans have three kinds of tears--basal, irritant and emotional. Basal tears keep our eyes lubricated and prevent damage. Irritant tears occur when our eyes are bothered by debris. Emotional tears are secreted as a result of intense emotions. Emotional tears contain hormones which can help relieve stress.

Question 11 of 20 Correct

When you sneeze or cough, how far can a virus travel?

Correct! Sorry, that’s incorrect.

The correct answer is: Cover your cough! Droplets of virus released during a cold or sneeze can travel as far as 12 feet. You may think you're safe by sitting on the other side of the cough from a sick person, but you could be in dangerous territory.

Weird Body Facts
Question 12 of 20 Correct

What percentage of wisdom teeth are eventually removed?

Correct! Sorry, that’s incorrect.

The correct answer is: Over 80 percent of all wisdom teeth are removed. Wisdom teeth are not necessary to the function of a healthy mouth. Wisdom teeth, the third set of molars, are the last teeth to come in--typically in the late teens and early twenties. Many times, jaws are not large enough to hold the new teeth, so they have to be removed.

Weird Body Facts
Question 16 of 20 Correct

How many times a day does the average person pass gas?

Correct! Sorry, that’s incorrect.

Weird Body Facts
Question 17 of 20 Correct

True or false: Children are more likely to be bitten by mosquitoes because their blood smells sweeter than the blood of an adult.

Correct! Sorry, that’s incorrect.

The correct answer is: This is false. Children are often bitten by mosquitoes more than adults--but not because of the way their blood smells. Children have less body hair than adults, and hair often warns a person when a mosquito has landed on their body. Without the hair, children don't feel the slight tickle from a mosquito and they don't swat them away.

Weird Body Facts
Question 18 of 20 Correct

What is the role of ear wax?

Correct! Sorry, that’s incorrect.

The correct answer is: Earwax protects the delicate inner ear from invading dirt and debris. When you remove earwax with a cotton swab, you're removing your body's natural protection against possible ear problems.

Weird Body Facts
Question 19 of 20 Correct

True or false: The biceps is the strongest muscle in the body.

Correct! Sorry, that’s incorrect.

The correct answer is: This is false. Pound for pound, the strongest muscle in your body is in your mouth--your tongue.

Weird Body Facts
Question 20 of 20 Correct

What is the role of the spleen?

Correct! Sorry, that’s incorrect.

The correct answer is: The spleen, an organ on the left side of your abdomen, filters your blood and removes particles and microbes that could cause an infection. You're likely to forget your spleen is there--unless it becomes enlarged or is damaged as a result of an accident. In that cause, it may need to be removed. You can live a fairly normal, healthy life without a spleen, though the risk of infection is higher without it. An infection can become more life-threatening if you don't have your spleen.
