The brain is the most miraculous and multifaceted of all body parts;the most intriguing and mystifying part of the human body. It is the most complex organ in the human body and probably the most complex creation present on this universe. The human brain with its complexity acts like a storage device which holds safely a person’s most cherished memories. Here are some of those facts about our brain 1.The typical brain is about 2% of a body’s weight but uses 20% of its total energy and oxygen intake. 2.It is the fattest organ in the body, contains 100 billion neurons or nerve cells (15 times the total human population on earth) and a trillion glial cells and has around 150,000 miles of blood vessels. 3.Ninety minutes of sweating can temporarily shrink the brain as much as one year of aging. 4.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. 5.Only 5 minutes without oxygen can cause brain damage. 6.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. 7.The human brain is the only organ in the human body that lacks nerves despite the fact that it acts as the central command for the central nervous system. This simply implies that, the human brain feels no pain. 8.Your brain generates about 12-25 watts of electricity. This is enough to power a low wattage LED light. 9.Our brains are getting smaller. Over the past 10-20,000 years, the size of the average human brain has shrunk by the size of a tennis ball. 10.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. 11. Physical exercise is just as important for the brain as it is for the rest of the body. In a recent study published in the annals of internal medicine suggest that exercise can delay the age at which people may get Alzheimer’s disease by more than 30% as it improves and makes more regular the blood flow to the brain. 12.It is also a myth that getting forgetful is an inevitable part of aging. Earlier the brain was thought to be hardwired, however, Neuroscientists have developed computer programs that can halt slow down and even reverse memory loss by 10 years. 13.On an average, humans experience around 70,000 thoughts each day. Laughing at a joke requires activity in five different areas of the brain.Forgetting unnecessary things is actually good for the brain as it helps the nervous system to maintain its plasticity.
