Jetëgjatësia

Jetëgjatësia refers to the length of time an organism lives. It is a fundamental biological characteristic that varies greatly across species and is influenced by a complex interplay of genetic and environmental factors. For humans, average life expectancy has significantly increased over the past centuries due to advancements in healthcare, sanitation, and nutrition. However, individual lifespans can still be affected by lifestyle choices, such as diet, exercise, and exposure to pollutants or diseases.

The study of jetëgjatësia, often referred to as gerontology or demography, seeks to understand the mechanisms behind aging and the factors that contribute to longevity. Research in this field explores cellular processes, genetic predispositions, and societal influences that impact how long individuals and populations survive. While a definitive maximum lifespan for humans is still a subject of scientific inquiry, understanding the determinants of jetëgjatësia is crucial for public health initiatives and for improving the quality of life for individuals as they age. Different populations around the world exhibit variations in life expectancy, often linked to socioeconomic conditions and access to resources. The pursuit of extending healthy lifespans, not just the total duration of life, is a growing focus in scientific research.
