Humans are the finest creatures on Earth, and their brains are the best in structure and function. We (humans) own that finest organ, and we need to be so proud of it. Here are some facts:

• Human brain at birth weighs about 400 grams.
• The most rapid growth of the brain occurs in the womb and in the first 4 months of life.
• By the age of 3 years, the brain weight is about 1400 grams, which is almost the size of an adult brain. Brain growth will however continue until the age of 18 years.
• An average male brain weighs about 1360 grams, while that for a female is 1275 grams. However, there is no evidence of a relationship between the size of the brain and the level of intelligence.
• The brain starts to shrink at the age of 50 years. By the age of 75 years, a brain looses about 25% of its size. However this natural decrease in size is not associated with intellectual deterioration.
• Everything we do is electrically generated. The brain is the biggest electricity generator of the body.

  

• The functional unit of the bran is the neuron. There are around 100 billion neurons concentrated in the grey matter.

  

• Each neuron connects with other neurons via electrical connections called “synapses. The number of these synapses reaches 100 trillions.
• A normal brain requires in 24 hours in normal circumstances the following: 1000 litres of blood, 71 litres of Oxygen ( only 4% of that is used), 100 grams of glucose ( only 10% of that is used), 71 litres of carbon dioxide is released, and 7% of lactate is produced.
• Only about 14% of brain ability is used, and the maximum usage was found to be about 17%.

Just imagine how much of the human brain power is reserved for different circumstances, and how much of the brain power is not used?. What will happen if any one of us manages to use just an extra 1% of brain?.
