What is the life expectancy?

Life expectancy is a statistical measure that estimates the average age a person is expected to live based on current mortality rates. It is often used by public health organizations and governments to assess the overall health and well-being of a population.

Factors that can influence life expectancy include genetics, lifestyle choices (such as diet and exercise), access to healthcare, socioeconomic status, and environmental factors.

Life expectancy can vary greatly between different populations and countries. In general, life expectancy has been increasing globally over the past few decades due to improvements in healthcare, sanitation, and living conditions.

According to the World Health Organization, the global average life expectancy at birth in 2019 was 72.6 years. However, there are significant disparities between countries, with some regions having much lower life expectancies than others.

It is important to note that life expectancy is a statistical measure and does not predict the lifespan of any individual person. Many external factors can affect an individual's life expectancy, and there is always some degree of uncertainty involved.
