People are living longer than before. It is a good thing for the society, but it also brings some problems. For example, people may suffer from loneliness after retirement. They need to find new friends or family members who can share their life and make them feel happy. In addition, they need to plan their future carefully to avoid financial problems because of health care cost. If they are not healthy enough, they will have to spend more money on medical treatment and medication. On the other hand, it can be beneficial for a country if its citizens live longer lives because it means that there will be fewer people taking up jobs and there will be more people paying taxes at the same time.
