Each year, the number of death tolls in America is increasing. Certain diseases contribute to the faster rate and the life expectancy in the US continues to decrease.

Since the World War II years, it was reported that the US life expectancy has increased. It was due to the advent of advanced medical technologies, efficient health forums, and proper nutrition and education, and public health procedures.

However, the Associated Press reported that the life expectancy made a big turn since last year. Eight out of 10 people died in 2015, which became a concern to health experts. According to S. Jay Olshansky, a public health researcher at the University of Illinois-Chicago, people will start to experience a threatening circumstance in a few years.

"With four years, you're starting to see some indication of something a little more ominous," Olshansky said.

It was also recorded that in 1980 and 1993, one-year life expectancy decreased due to the nasty flu season and AIDS respectively.  Meanwhile, it was also reported that the United States is surpassed by dozens of other first-world countries in terms of the life expectancy. Over 200 countries, the US ranked in the 43rd spot.

Monaco, Japan, Singapore, Macau, and San Marino are ranked as the top five. In an average, an American born in 2015 is expected to live for 76.3 years while Japanese can live up to 90 years.

According to the USA Today, males are likely to live shorter than the females. In the US, the common major diseases cause the increase mortality rate. Cancer, heart disease, stroke, chronic respiratory diseases, kidney disease, diabetes, unintentional injuries, and Alzheimer's disease are the main culprit. Suicide is also a part of the list.
