There is a lot going on inside your head. Every action, reaction and creative impulse starts in the brain.

Thomas Edison once said, “The chief function of the body is to carry the brain around.”[1]

Stephen Hawking said, “Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious.” [2]

Justin Bieber said, “I'm crazy, I'm nuts. Just the way my brain works. I'm not normal. I think differently. My mind is always racing.”[3]

Which one can you most relate to?

The human brain is constantly being studied and researched with new details emerging all the time. Here are 10 interesting facts that you may want to think about:

1.     The popular myth that we use only 10% of our brains is flat-out wrong. Brain scans clearly show that we use most of our brain most of the time, even when we’re sleeping. [4]

2.     More than 100,000 chemicals reactions take place in your brain every second.[5] 

3.     The typical brain is about 2% of a body’s weight but uses 20% 
of its total energy and oxygen intake.[6]

4.     Your brain weighs about 3 pounds. Of that, the dry weight is 60% fat, making your brain the fattest organ.[7]

5.     We are not getting smarter. Since the Victorian era, average IQs have gone down 1.6 points per decade for a total of 13.35 points.[8]

6.     Our attention spans are getting shorter. In 2000, the average attention span was 12 seconds. Now it’s 8 seconds. That’s shorter than the attention span of the average goldfish, which is 9 seconds.[9]

7.     Your brain’s storage capacity is considered virtually unlimited.
It doesn’t get “used up” like RAM in your computer.[10]

8.     Your brain starts slowing down at the ripe old age of 24 but peaks for different cognitive skills at different ages. In fact at any given age, you’re likely getting better at some things and worse at others.[11]

9.     The brain in your head isn’t your only brain. There’s a “second brain” in your intestines that contains 100,000 neurons. Gut bacteria are responsible for making over 30 neurotransmitters including the “happy” molecule serotonin.[12]

10. Brain information moves at an impressive 260 miles per hour. This is faster than Formula 1 race cars which top out at 240 mph.[13]

What an amazing machine! But, what about the thoughts that flow out of this intelligently designed organ? How do we arrive at our thoughts and can our mind ever change?
