In most parts of the world people are living longer. What are the possible causes of this situation? Is this a negative or positive development?

In recent years, people's age is increasing in almost countries and there are reasons behind

this

trend. In my view,

this

issue brings more benefits than disadvantages

for

Suggestion

to

society.

First

, the strong

development

of medicine, especially the invention of the vaccine to prevent most diseases that has significantly contributed to the increased

life

expectancy. In these days, when children are born, they are vaccinated with many vaccines to prevent many diseases throughout their lives.

For example

, tetanus, chicken pox, rubella, ...

Second

, the outstanding

development

of cutting-edge technology treatment techniques so that it increases the accuracy of diagnosis and the success rate for surgeries, as transcranial Doppler

celtrasound

, positioning system applications in brain

tumor

an abnormal new mass of tissue that serves no purpose

surgery, ... Futhermore, better social security in which the care for the elderly has been increasing attention so that

this

reason has helped people to live longer. So the reasons mentioned above bring a happy

life

, since those who

with their families, make contributions to social progress.

That is

not to say that the trend will be beneficial. Because of increased

life

expectancy means a large population, as well as an increase in the proportion of people who outside the working age and rely on welfare system so that

this

problem becomes a burden and a restriction to the

development

of poor countries. In conclusion, the increase in human

life

expectancy is positive or negative rely on the

development

of each nation.

This

means that

for

in

countries where high-income citizens who have accumulated retirement savings and

been

the state or fact of existing

being

able to afford high-end health care service,

that is

a positive phenomenon.

In contrast

, it is a difficult problem for poor countries, which have little national budget and have to pay social welfare for non-working-age citizens whose numbers are increasing. Regardless of

of a society worth living.
