You are your brain!
Think deeply about it, you live in your brain. Your brain defines your life. Your brain works 24X7 without taking any break (not even in sleep!). No doubt brain is the most important organ of our bodies. Though its only 2% of body mass but it consumes more than 20% of energy supplied to body.
Your brain is an approx. 1.5 Kgs universe that processes 70,000 thoughts each day using 100 billion neurons that connect at more than 500 trillion points through synapses that travel 300 miles/hour. Wow, it’s so much for a small organ.
