People expect too much of medical science as the the advances in medical science have successfully cured many diseases that was incurable in the past. For example, small pox, a disease which have took millions of life, have been eradicated with vaccines in the 20th century when they were known to be incurable in the past. With such successful cases, they expect the advancement of medical science to be able to cure the diseases for them. People take it for granted that almost all diseases can be cured. They start to be less cautious of their surroundings and take their health for granted. For instance, there are some people who are under medication to control their high cholesterol but they still do not change their diet to improve their cholesterol. They may continue to eat food which may harm them. They may have the mentality that the medication will help them do the job of controlling their high cholesterol and expect the medication to do the job for them instead of controlling and changing their diet to a healthier one. Therefore, people expect too much of medical science as they rely heavily on medical science.
