Human and diseases are inextricably linked together right from the beginning . Lot of advances in medical fields now have made it possible to control them and consequently we have longer life span than ever. Although some people may believe that there are some drawbacks but in my opinion their benefits are far outweighing them.
Admittedly, there might be some obvious disadvantages. Firstly, in later ages it might be difficult for some people to maintain their health and they might have to pay medical bills for it. Secondly, there might be less working force because as mortality rate is dropped , there will be more elderly people which will not be capable of doing normal routine work. Denmark, for instance, have high life expectancy rate and as a result the number of people getting retired is rising. Because there death and birth rate is almost equal so they have to open the door for skillful immigrants to fill this gape.
Nevertheless, despite the drawbacks above, I strongly believe that benefits are humungous. These medical advances have pretty much alleviate the most of the epidemic , which were threatening the humanity from his birth. Plague, for example, have wiped out several cities and even civilizations from the face of earth in matter of weeks. Our thriving civilization is a proof that we have stopped it. Because of these advances we have now succeeded to cure contagious diseases such as malaria and cholera. Sophistication in machinery , furthermore, have made it possible to perform impossible operations like kidney and heart transplant. These all factors are playing pivotal role in enhancing life expectancy rate.
In conclusion, alleviating pandemics , making it possible to perform difficult operations and prolonging life expectancy rate are overcoming its disadvantages.
