The document summarizes findings from a large study on global life expectancy and causes of death conducted by the Institute of Health Metrics and Evaluation. Some key findings included:
1) Lifespans have increased almost everywhere over the past few decades, though some countries like those affected by HIV/AIDS have seen decreases. The risk of death for children under 5 has dropped significantly.
2) The study found that malaria kills over twice as many people annually than previously believed, with many adult deaths contrary to prevailing theories of immunity.
3) As communicable diseases decline in some regions, non-communicable "lifestyle" diseases are a growing cause of death, while rates of disability are not declining globally.
