Traditionally, the term "elderly" is commonly used to refer to individuals aged 65 and older. This age is significant as it is when most people retire and start receiving a pension. However, its important to note that the age of elderly can be impacted by genetics, lifestyle, and overall health, and there are alternative viewpoints on what age is considered elderly. For instance, one study classified older adults into the young old (60 to 69 years), the middle old (70 to 79 years), and the very old (80 years and older) . Additionally, in some cultures, the age at which a person is considered elderly may differ. For example, Japan classifies individuals under 75 as "pre-old". Therefore, while 65 is the traditional age at which a person is considered elderly, its essential to consider individual health, lifestyle, and cultural perspectives when defining this term.
