EDUCATION: _____ _____ Prologue: Human life is the best creation of evolution and it has got two aspects: the biological and the socio-cultural. Biological aspect is found in plant and animal life. But the socio-cultural aspect is the rare distinction of human life alone. Our life in the complex world is governed not only by the biological process, but also by a social process. While the functioning of the organism is the biological heredity, education is his social heredity. With biological heredity alone, he would be nothing better than an animal. But he has social heredity that makes him a man who is now capable of governing this world. Education is vital process of social life. Without education human race would be no better than animal race. Eating, drinking, sleeping and sexual life are common to both animals and men. It is only knowledge and education, where they differ. The […]
Development of Nation: _____ _____ Prologue: When evolution of human species occurred, all humans all over the world were same. Most people have lost sight of the fact that a short time ago—very short in terms of the life span of the earth—people were nomadic food gatherers, garnering an existence as best they could from what nature threw their way. It has been only about 10,000 years since the Neolithic Agricultural Revolution, when people changed from food gatherers to food producers. Throughout most of subsequent human history, civilizations have been based on a comfortable life for a privileged minority and unremitting toil for the vast majority. Only within the past two centuries, ordinary people are able to expect leisure and high consumption standards, and that only in the world’s economically developed countries. The total major countries of the world are 188 out of which only 32 are developed and remaining […]
EXERCISE: _ _ Prologue: The big four “proximate” causes of preventable ill-health are: smoking, poor nutrition, lack of physical activity and alcohol excess. Of these, the importance of regular exercise is the least well-known. However, exercise is not a new concept. In 300 BC, Aristotle suggested that “a man falls into ill health as a result of not caring for exercise.” These factors (smoking, nutrition, lack of physical activity and alcohol) are often described as lifestyle choices, yet many people do not have the finances, self-efficacy, environment or knowledge to be able to practice lifestyle choices correctly. We have moved towards a sedentary society with changing work and domestic habits & patterns. We now drive cars, sit in front of computers or TVs and use domestic appliances. There are far fewer manual jobs. This means that physical activity is not routine for most people. In 1949, 34% of miles travelled […]
PULSE OXIMETRY _____ Prologue: All of us know how important oxygen is for our survival. Hypoxia means low oxygen supply and/or utilization by organ or tissue. Hypoxemia means low oxygen content of arterial blood. Hypoxaemia invariably leads to hypoxia but hypoxia can occur even without hypoxaemia. Arterial blood oxygen saturation is now considered the 5th vital sign, joining: temperature, respiratory rate, heart rate and blood pressure. Hypoxemia can be present before recognizable signs of respiratory distress become evident and the traditional sign of circumoral cyanosis is a late indicator of decreased oxygenation. Blood gas analysis was for many years the only available method of detecting hypoxemia in critically ill patients, but this technique is painful, has potential complications, and does not provide immediate or continuous data. Pulse oximetry is an objective estimation of oxygenation, and it is simple, reliable, and accurate when used appropriately. It has the unique advantage of […]
YOGA: _ Marilyn Monroe performs dhanurasana (bow pose) in 1948: Indra Devi opened yoga studio in Hollywood in 1948 and discovered ready students among movie stars, who found yoga’s breathing and relaxation techniques useful to their work. Her students included Greta Garbo, Gloria Swanson and Marilyn Monroe. ______ Prologue: A considerable number of studies have identified prayer as a frequent and favoured coping method among patients providing each patient with comfort and strength. A variety of studies have attempted to test the efficacy of prayer and found no medical benefit. Prayers offered by strangers had no effect on the recovery of people who were undergoing heart surgery, a large and well-constructed study proved in 2006. The Cochrane Collaboration published a thorough review reaching the same conclusion in 2011 and counselled, “We are not convinced that further trials of this intervention should be undertaken and would prefer to see any resources […]
