human brain..miracle from the god

It is becoming more and more evident that information does not equal adept use of the mind. Most of us have never been taught how to think and how to effectively create.
Mind health is not about cramming it with information but about the ability to consciously control your mind and hence your world
Your brain is a thinking organ that learns and grows by interacting with the world through perception and action. Mental stimulation improves brain function and actually protects against cognitive decline, as does physical exercise.
The human brain is able to continually adapt and rewire itself. Even in old age, it can grow new neurons. Severe mental decline is usually caused by disease, whereas most age-related losses in memory or motor skills simply result from inactivity and a lack of mental exercise and stimulation. In other words, use it or lose it.

It takes time and effort to cultivate emotional health, but there's a huge payoff. The more you make healthy choices that strengthen your emotional health, the better you'll feel. The good news is you can learn to handle stress, rise to meet challenges, bounce back from disappointment, stay healthy, and enjoy your life.. For workers everywhere, the troubled economy may feel like an emotional roller coaster. "Layoffs" and "budget cuts" have become bywords in the workplace, and the result is increased fear, uncertainty, and higher levels of stress. Since job and workplace stress increase in times of economic crisis, it's important to learn new and better ways of coping with the pressureEmotionally healthy people can manage stress and their emotions. They bounce back when bad things happen, build strong relationships and lead productive, fulfilling lives

despite the brain's role as the 'master organ' governing sexual function , little is known about relationships between brain and sexual health.In 2005, Dr. Gert Holstege at the University of Groningen in the Netherlands used positron emission tomography to scan the brains of men and women during orgasms. He discovered, among other changes, a sharp decrease in activity in the amygdala, the brain region involved in processing fearful stimuli. Aside from causing pleasure, sex clearly lowers fearDr Fisher explained in a lecture at the 2004 American Psychiatric Association's annual meeting, is not an emotion. Rather, it's "a motivation system, it's a drive, it's part of the reward system of the brain." It's a need that compels the lover to seek a specific mating partner. Then the brain links this drive to all kinds of specific emotions depending on how the relationship is going. All the while, she went on to say, the prefrontal cortex is assembling data, putting information into patterns, making strategies, and monitoring the progress toward "life's greatest prize."
Love also hurts. Dr Fisher cited one recent study where 40 percent of people who had been dumped by their partner in the previous eight weeks experienced clinical depression and 12 percent severe depression. It is estimated that 50 to 70 percent of female homicides are committed by lovers and spouses. Annually one million women and 400,000 men are stalked.
Dr Fisher divides love into three categories involving different brain systems: 1) Lust (the craving for sexual gratification), driven by androgens and estrogens; 2) Attraction (or romantic or passionate love, characterized by euphoria when things are going well, terrible mood swings when they're not, focused attention, obsessive thinking, and intense craving for the individual), driven by high dopamine and norepinephrine levels and low serotonin; and 3) Attachment (the sense of calm, peace, and stability one feels with a long-term partner) driven by the hormones oxytocin and vasopressin.

Adequate sleep is crucial to proper brain function - no less so than air, water, and food - but stress can modify sleep-wakefulness cyclesAny amount of sleep deprivation will diminish mental performance, cautions Mark Mahowald, a professor of neurology at the University of Minnesota Medical School. "One complete night of sleep deprivation is as impairing in simulated driving tests as a legally intoxicating blood-alcohol level".Previous work by Dr. Van Cauter, a professor of medicine at the University of Chicago, found that "metabolic and endocrine changes resulting from a significant sleep debt mimic many of the hallmarks of aging. We suspect that chronic sleep loss may not only hasten the onset but could also increase the severity of age-related ailments such as diabetes, hypertension, obesity, and memory loss
