Apa itu Aging?

Proses penuaan (aging process) merupakan suatu proses yang alami ditandai dengan adanya penurunan atau perubahan kondisi fisik, psikologis maupun sosial dalam berinteraksi dengan orang lain (Handayani, dkk, 2013).

• Primary aging is  normal,  diseasefree development during adulthood.
• Secondary aging is developmental changes that are related to disease, lifestyle, and other environmentally induced changes that are not inevitable (e.g., pollution).
• Tertiary aging is the rapid losses that occur shortly before death.
