Ageing. Definition
Ageing
Ageing can be defined as a gradual change in an organism that leads to increased risk of weakness, disease, and death. It takes place in a cell, an organ, or the total organism over the entire adult life span of any living thing. There is a decline in biological functions and in ability to adapt to metabolic stress. Changes in organs include the replacement of functional cardiovascular cells with fibrous tissue. Overall effects of aging include reduced immunity, loss of muscle strength, decline in memory and other aspects of cognition, and loss of color in the hair and elasticity in the skin. In women, the process accelerates after menopause.
Ageing is the accumulation of changes in a person over time. In humans, it refers to a multidimensional process of physical, psychological, and social change. Some dimensions of ageing grow and expand over time, while others decline. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand. Research shows that even late in life, potential exists for physical, mental, and social growth and development. Ageing is an important part of all human societies reflecting the biological changes that occur, but also reflecting cultural and societal conventions. Roughly 100,000 people worldwide die each day of age-related causes.
Health and Wellbeing in Ageing
Health is related to the process of ageing in that the health of a person deteriorates as they grow older; deteriorates in the sense that a person is not as fit physically in older age as he or she was in his or her youth. Some age-related physical changes are obvious: an extra laugh line or two, graying hair, and additional weight around the midsection, for instance. But many changes, such as the gradual loss of bone tissue and the reduced resiliency of blood vessels, go unnoticed, even for decades. Even though a person is not aware of them, they're happening, nevertheless. Knowing how and why our body
