Gerontology

consists of ages nearing or surpassing the life expectancy of human beings

In a broader sense, ageing can refer to single cells within an organism which have ceased dividing, or to the population of a species.

Sustainability of an aging society depends on our effectiveness in creating technological environments, including assistive technology and inclusive design, for innovative and independent living and social participation of older adults in any state of health, comfort as well as safety. In short, gerontechnology concerns matching technological environments to health, housing, mobility, communication, leisure, wor
