Uno es su propio cerebro
Your brain determines every aspect of your life and without your brain, there is no self and no awareness of the world.
Your brain is a three pound 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.
The signals that travel through these interconnected neurons form the basis of memories, thoughts and feelings.
Throughout your life your experiences create patterns of activity that explain how our brains code our thoughts, memories, skills and sense of self.
El cerebro envejece al igual que el resto del cuerpo: se reduce de tamaño, disminuye su velocidad y se vuelve menos adaptable al cambio.
