Solitary death

I read the article about solitary death caused by Hanshin Awaji Earthquake. There are 66 cases that the elderlies die alone. Some of their bodies were found a month after their death. I think that it is problem that the number of the elderlies' death by theirselvs. They experienced such a terrible disaster, then they live by their selves(since their parters went away...) and die alone. It's very sorrowful, I think. To solve the problem, there are some services that inform someone that the aged is alive or in danger. Therefore the government should forse people to put the service like this.
