I would like to talk about health expectancy. Health expectancy is a term which people can live without nursing and disease. It is proposaled by WHO in 2000 to suggest that it is important that live long healthy not only to live long. According to the survey of Nippon economic news, life expectancy in Japan is 73.3 old and it is longest in the world. On the other hand, life expectancy in Japan is 83. We should think that how we spend our time which is between health expectancy and life expectancy. In addition, life expectancy is longer and longer now, so it is necessary to change system such as the retirement age.
