Ears Emit Sound 
Did you know that healthy ears actually emit sounds? These sounds are usually very soft, but can occasionally be heard by others. Surprisingly, the sounds are rarely heard by the person whose ear is emitting the sounds! The cause of these sounds is still under debate, but is thought by some to be due to input from the central nervous system.

Brain Uses 20% of Oxygen Breathed 
Although the brain accounts for only 2% of the whole body's mass, it uses 20% of all the oxygen we breathe. A continuous supply of oxygen is necessary for survival. A loss of oxygen for 10 minutes can result in significant neural damage.

Reading Aloud Stimulates Child Development

Reading aloud to children helps stimulate brain development, yet only 50% of infants and toddlers are routinely read to by their parents.

Yawns. It is thought that a yawn works to send more oxygen to the brain, therefore working to cool it down and wake it up.

Emotions. The capacity for such emotions as joy, happiness, fear, and shyness are already developed at birth. The specific type of nurturing a child receives shapes how these emotions are developed.

World Champion. A world champion memorizer, Ben Pridmore memorized 96 historical events in 5 minutes and memorized a single, shuffled deck of cards in 26.28 seconds.

Thoughts. The average number of thoughts that humans are believed to experience each day is 70,000.

Albert Einstein. Einstein’s brain was similar in size to other humans except in the region that is responsible for math and spatial perception. In that region, his brain was 35% wider than average.

A piece of brain tissue the size of a grain of sand contains 100,000 neurons and 1 billion synapses all communicating with each other. 

Brain information moves anywhere between 1 mph and an impressive 268 miles per hour. This is faster than Formula 1 race cars which top out at 240 mph!

Multitasking makes you less productive. When you multitask, your brain simply rapidly toggles back and forth between tasks. This results in decreases in attention span, learning, performance, and short-term memory.

Intelligence increases success at work and in everyday life It is a well-known fact that intelligent people are more successful. In his 2001 publication, Robert Sternberg from Yale University discusses the relationship between intelligence and success, and concludes: A person's intelligence influences their salary by 15%.

Studies show that inactive brain cells degenerate over time. On an average day, a person loses between 100,000 and several million brain cells. Particularly affected are the most inactive areas of the brain. In this regard, you can compare the brain to a muscle, degenerating if neglected.

Studies show that brain training increases fluid intelligence Our intelligence consists of two elements: the crystallized (factual knowledge) and fluid intelligence (capacity for problem solving and logical thinking). With her groundbreaking 2008 study, scientist Dr. Susanne Jaeggi was able to prove that fluid intelligence can be improved by 40% through scientific brain training.
