Human ageing is a natural process that occurs over time, characterized by gradual physical and biological changes. As people age, their bodies may experience a decline in cellular function, leading to reduced strength, flexibility, and endurance. Common signs of ageing include wrinkles, grey hair, and a decrease in bone density. The ageing process is influenced by various factors, including genetics, lifestyle, and environmental conditions. While some aspects of ageing are inevitable, healthy habits such as regular exercise, a balanced diet, and avoiding harmful substances can help improve quality of life and longevity. Understanding human ageing can aid in developing strategies for healthier ageing.
