The worry of the person of the young generation seems to doubt whether the pension can be gotten after it retires. The pension that receives after people of the baby boom generation retire is supported by people of young people of the nowadays. Worry that it becomes impossible for people of young people of the nowadays to get the pension when thinking that the number of pensioners increases might be caused. However, when the pensioner of the baby boom generation leaves, I will cancel worry. I can say that Japan sinks when it becomes impossible for any generation's people to get the pension.
