The study was led by Justin Denney, PhD, assistant professor of sociology at Rice University. Researchers collected data from the Human Mortality Database for 1930-2000 to predict future life expectancy in 2055. Based on this research, not only has life expectancy stagnated in America, it trails several developed countries.
For an American born today, life expectancy is around 78.49 years of age. Compared to countries with the highest life expectancies, Americans may be missing out on five to 10 years of life. Monaco has the highest life expectancy at 89.68 years while Macau at 84.43 and Japan at 83.91 are close behind. Imagine getting an extra decade to experience life and that's what many Americans are missing out on.
