Old people stacking up like cords of wood.
https://www.nytimes.com/2017/11/30/world/asia/japan-lonely-deaths-the-end.htmlWith no families or visitors to speak of, many older tenants spent weeks or months cocooned in their small apartments, offering little hint of their existence to the world outside their doors. And each year, some of them died without anyone knowing, only to be discovered after their neighbors caught the smell.
The first time it happened, or at least the first time it drew national attention, the corpse of a 69-year-old man living near Mrs. Ito had been lying on the floor for three years, without anyone noticing his absence. His monthly rent and utilities had been withdrawn automatically from his bank account. Finally, after his savings were depleted in 2000, the authorities came to the apartment and found his skeleton near the kitchen, its flesh picked clean by maggots and beetles, just a few feet away from his next-door neighbors.
