Age | Vibepedia

Age refers to the duration of an individual's life, measured from birth, and is a fundamental aspect of human development, influencing physical, psychological, and social changes. The concept of age is complex, with various dimensions, including biological, psychological, and social age. According to the World Health Organization (WHO), the global population is aging, with the proportion of people aged 60 and over expected to increase from 12% in 2015 to 22% by 2050. This demographic shift has significant implications for healthcare, social security, and economic systems. For instance, a study by the National Institute on Aging found that the cost of healthcare for older adults in the United States is projected to increase by 25% by 2030. Furthermore, age is a critical factor in various social and cultural contexts, such as education, employment, and retirement, with many countries implementing age-related policies, like the Age Discrimination in Employment Act in the United States. The concept of age is also closely tied to other topics, including [[demography|demography]], [[gerontology|gerontology]], and [[sociology|sociology]].
