Everywhere in the world, people are living longer. Studies show the average age of the human population is rising. By the year 2050, an estimated two billion people will be aged 60 or older. And the number of people 80 years or older will have almost quadrupled to 395 million. That is the latest number from the United Nations’ World Health Organization.
* rise = 오르다, 올라가다/ estimate = 추산(추정)하다/ quadruple = 네 배가 되다/ latest = (가장) 최근의(최신의)
The WHO says governments must prepare now to deal with an increasingly aging world. As people age, they may develop long-term health problems. These disorders may affect their quality of life and create problems for society and health care systems. Caring for an aging population takes both time and money. The responsibility of caring for an older person often falls on family members. And this can create difficulties.
* increasingly = 점점 더, 갈수록 더/ long-term = 장기적인/ disorder = (신체 기능의) 장애(이상)/ quality of life = 생활(생명)의 질/ fall on ~ = ~의 책임(몫)이다
