             Life expectancy is a crucial metric used to measure the overall health and development of a country. 
             It represents the average number of years a person is expected to live based on various socio-economic, 
             environmental, and healthcare factors. By analyzing different aspects like mortality rate, immunization coverage, 
             GDP, and healthcare expenditure, we aim to predict life expectancy accurately.
