Medicine can do many things to benefit the average person. It can cure cancer and let people live longer. The average age of a person in the United States of America is about 77 years old. Is this a good thing? Perhaps not. What can a 77 year old person do besides benefit from social security? Many 77 year olds can not work. Do they serve a purpose? My opinion for that is no, the average 77 year old serves little to no purpose. So then I ask you again, is medicine good? It lengthens the lives of these old people so then we have to pay for their social security. Now I am not saying that we should kill the elderly I am just saying that we should let nature take its course.
