Several factors such as nutrition and effective nursing care are the significant reasons behind this.

The increased demands on elderly care facilities and the predominance of health expectancy among the elderly represent enormous challenges for industrialized countries. The provision of adequate nutrition and high-level, efficient nursing care are crucial factors determining people's longevity. For maintaining better health for all, the provision of quality labor and services is mandatory, which requires complex expenditure as life expectancy will increase in developed countries.
