Today we are relishing the ambrosial taste of the modern scientific technology and applications. Science and technologies are a part of all human activities, from the houses that we live in, the food we eat, the cars we drive, and to the electronic gadgetry in almost  every home that we use to remain informed and entertained. These all evidences show the blessings of scientific knowledge on humans.

Before eighteenth century we were plunged in the depths of ignorance and unawareness of scientific knowledge. Without having an adequate scientific knowledge, our ancestors had buried their common senses deep under the mask of ignorant prejudices but it was the scientific revolution in nineteenth century that unsheathed it and now we can see that the whole world is globalised : due to this scientific revolution. Science has affected human life and culture in manyways and requires numerous books to discuss its impacts on us. So in this essay my goal is only to describe the impacts on health and behaviour in comparison with the past and present.                 

Before the revolutionary changes in early nineteenth century,; health problems and a large number of fatal diseases gulped the whole community like a malicious dragon. The most common health problems were the numerous fatal diseases and epidemics. There was no cure for the most common diseases so these diseases always acted as a catastrophe. In those days emergence of an epidemic always proved 'Pandora's Box' to the whole locality. At that moment average life span was thirty to forty years. Some common diseases like Chicken pox, Measles, Typhoid and many different kinds of fevers had killed more than the present American population in last seven centuries through the whole planet. On the other hand if we analyse the ratio of mortality in year 1999 in comparison with the past, we would come to know that these diseases couldn't affect more than some thousands of human lives.

As the most descriptive condition of humans, health is very important factor for us. Without health we can't survive or by having a bad health we can't reach the average human life span. After the scientific revolution, the scientific applications have led to the treatment of numerous fatal diseases and health problems and now we are able to increase the average life span to more than seventy years. Now we can treat those fatal epidemics that ruined every human life on their way from city to city some centuries ago. By implementing many scientific techniques and methods we are now able to overcome these diseases. for example in the past we were unable to cure Chicken pox, but on the other hand now we can easily get rid of this disease. There are a lot of examples like that of Chicken pox which emphasise the impacts of science on health and fitness. The most common implications in the field of medicine and health are the sophisticated contribution of pharmacy and modern way of treatment. In the field of the pharmacy, we are now able to manufacture many curative medicines that have helped mankind to survive from these fatal diseases. Besides that, we are able to manufacture and invent many useful electronic equipment that help doctors to analyse or treat many diseases. The most common examples of these electronic applications are X-ray plants, Ultrasound, ECG (Electro Cardio Gram), and Kidney Transplantation equipments. On reviewing the scientific blessings we can say that without these equipments medical technology had no past and similarly can't have a future.

Before the revolutionary emergence of scientific knowledge, our ancestors were commonly illiterates and they were victims of different kind of misconceptions like superstitions, whims and magical tricks. These were the most effective aspects that acted as obstacles in the way of development of our ancestors and made them unable to think and reason on by their own. The most common superstitions that circumambulated in our ancestor's minds were the fear of black cats, number thirteen, and Nelson number. They considered them as signs of bad and good lucks. If we analyse the reason for that we will come to know that these are the consequences of the lack of knowledge. These different kind of superstitions acted as obstacle in their deeds and campaigns. The second most interesting consequence due to lack of knowledge was their believes and theories about the emergence of life, universe, earth, sun and many more explanations about the things they had no clue of.

When the sense of knowledge and reasoning developed in them they came to realise that they were wrong in their beliefs and there was no reality in the superstitions. It also helped them to provoke them to learn more and invent new things. It was only due to the scientific knowledge that they got rid of these misconceptions and enabled themselves to invent, discover, and to acquire better knowledge. The whole world is tied up in a single knot by this scientific development and a sense of competition is produced among all nations. These effects also changed their social behaviours and they adopted the senses of respect and manners for each other. I think that scientific knowledge acted as key to open the gates of better health improvements and sophisticated behaviour. So we should salute the scientific knowledge that enabled us to realise the reality of

life.
