Jetgjatësia

Jetgjatësia refers to the duration of a person's life. It is a complex biological and social phenomenon influenced by a multitude of factors. These factors can be broadly categorized into genetic predispositions, lifestyle choices, environmental exposures, and access to healthcare.

Genetics plays a significant role in determining an individual's potential lifespan. Certain genes are associated with longevity, while others may increase susceptibility to diseases that can shorten life. Lifestyle choices, such as diet, exercise, smoking, and alcohol consumption, have a profound impact on health and can either promote or detract from a longer life.

Environmental factors, including pollution, access to clean water, and the prevalence of infectious diseases, also contribute to variations in life expectancy across different populations and regions. Furthermore, the quality and accessibility of healthcare services, from preventative care to treatment of chronic conditions, are crucial in extending lifespans and improving overall health.

Globally, life expectancy has increased dramatically over the past century due to advancements in medicine, public health initiatives, and improved living standards. However, disparities persist, with certain demographic groups and geographical areas experiencing shorter lifespans than others. Research continues to explore the biological mechanisms of aging and identify interventions that could further promote longevity and healthspan, the period of life spent in good health.
