Taiwan has become an elderly society. Concerning the issue of aging, in the past, the elderly focused solely on medical aspects for their health, such as medical issues related to diseases, injuries, disabilities, medical care, etc. These health issues of medical care were all related to physical health. In recent years, the World Health Organization has advocated for active aging. Active aging is elderly-centered. It pays attention to the interaction and involvement between the elderly and the environment and how to assist the elderly in realizing their potential and to encourage community participation to achieve a holistic development of physical, social and psychological well-being. Nowadays, with the development of medical care and digital technology, aging focuses on positive views and holistic health. This article uses the Bronfenbrenner ecological systems theory to discuss the impact of the social environment on aging development and how society, technology and medical care can become active aging resources for the elderly. We aim to raise a positive awareness for everyone to take into consideration the formulation of elderly-friendly social environments in technological, medical and social levels.
