In the human body, blood circulates in vessels. There are arteries, veins, and capillaries. In arteries, there is oxygenated blood whereas in veins there is deoxygenated blood and capillaries are the smallest blood vessels in the human body. If these blood vessels are spread like a track, they will expand up to one hundred thousand miles and in all these blood vessels, blood does not circulate with the same pressure rather, in some of the vessels, the blood pressure is high whereas, in others, it is low. So, it is the brain that maintains this blood pressure, heartbeat with a specific rhythm, body temperature even the blink of the eye because it is the headquarter.
Now, what is the storage capacity of the human brain?
A mobile phone may have 64 GB storage capacity whereas a laptop, 1 TB. According to Western University, USA, the storage capacity of the human brain is 2.5 PB. It means that it can store whatever you have seen on television for three hundred years and according to the latest research, it is limitless.
Like physical exercise, there is mental exercise as well and what is that exercise?

Before 1990, human brain was a black box (mystery) but in 1990, when MRI (magnetic resonance imaging) techniques were invented and the working of a living human brain was observed, we came to know that there are neurons like tracks or pathways in the brain and when a human does reading, these pathways (neurons) expand.
For example, on a road, there is a stream of traffic moving in a specific flow but if the traffic increases, the road will have to be broadened. Similarly, the tracks of the human brain also broaden.
What is the weight of the human brain? It is almost 1.5 kg. An elephant’s brain weighs about 4 to 5 kg whereas a blue whale’s brain weighs 9 kg.
An animal brain is bigger but a human brain is smarter. Allah Almighty has granted the human brain a lot of capabilities. What a great blessing it is! But we should ask ourselves how we use this blessing of Allah Almighty.
This brain is not a dustbin to put hatred, coercion, backbiting, grudges, and enmity in it rather it is a treasure-chest which should have the feelings of love, harmony, and tolerance in it.
