These days, people are by and large living longer. Besides, their life expectancy is increasing in order to due to some several factors of these phenomenons. As far as I am concerned, these factors are invention of antibiotic injection, abundant nutrientious foods, and health care insurance.
The possibility of medical improvement has been affected by the invention of antibiotic injection so far. In the past, most people were exposed to danger of epidemic diseases due to lack of sanitation. In addition, few kinds lack of medicine made people get these diseases more easily. On the other hand, invention of antibiotic injection such as peniciline has saved people from epidemic diseases, and dedication of antibiotic study has made more types of medicine. Therefore, this invention has lead people to live longer as it prevents people death from these plagues.
Moreover, people can live longer because of the abundance in nutritious food. nutrient food and abundance of this. Most technology in agriculture has been developed so it consequently causes increase in production of food. Thus, less more people have been saved from starving and death since the major death of the people in the past was famine. It Increase in food yields also deters people getting old easily now by providing nutrient foods to them.
Another reason why people are living longer is health care insurance. Before this insurance system appeared, many people could not afford to pay for their medical service bill like medication or surgery because this was too expensive for individuals to pay for it. However, many people have signed up insurance. Therefore, most people in the world do not need to worry about the medical service bill at all now.
By invention of antibiotic injection, increase of food production and nutrientious food, people get much longer lives in compared to the past. These are still the major causes of living longer but the distribution of these assets is still not fair enough. Therefore, equal distribution of them needs to be executed now. |
