Scientists at the University of Texas Health Science Center at Houston and the Harris County Institute of Forensic Sciences (IFS) in Texas have uncovered some of the key factors related to premature deaths among adults.
They have now published their results in the journal PLOS One.
A 2016 report that the Centers for Disease Control and Prevention (CDC) compiled found that more than 2 million people in the United States die every year.
The leading causes of death in the U.S. are heart disease and cancer, with around 635,000 deaths and 600,000 deaths per year, respectively.
