The brain is an amazing organ functioning inside the living organisms. It is an organ of soft nervous tissue contained in the skull of vertebrates, functioning as the control center of emotions and intellectual and nervous activity [1]. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving the flow of chemicals called hormones. Moreover, neurotransmitters aka chemical messengers help to transmit neuro-signals from one neuron to another. The combination of these two agents moderates our feelings of well-being, and lifestyle factors affect them. Hence, it will be beneficial for us, as living beings, to know how these can affect our day-to-day activities. Most importantly, it will be more helpful to know the ways we can manipulate the presence of them to improve our productivity.
