Among their findings: Life expectancy for Korean women born in 2030 in South Korea will expect to have life expectancy of 90.8 years, French women 88.6 years, and Japanese women 88.4 years.
Significantly, life expectancy is predicted to increase least in Macedonia, Bulgaria, Japan and the U.S. (1.4, 1.5, 1.8 and 2.1 years) for women, and in Macedonia, Greece and Sweden and the U.S. (2.4, 2.7, 3.0 and 3.0 years) for men. For men, Australia, Switzerland, Canada and the Netherlands were next, all with an expectancy of almost 84.
Australian women are far more likely to live longer than their male counterparts, with an average predicted life expectancy in 2030 of approximately 87 to 88 years.
Some possible reasons? We beat out other high-income countries in factors we don't want to be ahead for: body mass index (BMI), homicides, and child and maternity mortality-all which are contributing to our shorter lives.
The 2030 life expectancy projection for Americans is 83-years-old for women and 79-years-old for men.
Methuselah lived to the age of 969 in the Bible.
Imperial College London and the World Health Organization analysed lifespans in 35 industrialised countries.
A century ago, the USA had some of the tallest people in the world, a marker of good nutrition early in life.
This is down from a gap of four years for Britons born in 2010 - men born at the start of the decade are expected to live until 78.3 and women until 82.3.
"I think the difference between life expectancy in Indigenious and non-Indigenous is one of our most notable, persistent and discouraging differences that we've seen in mortality in Canada". The report is not unwise to this obligation, specifically stating it is "important" policies are formulated and put in place to support a growing older population.
This is thought to be due to factors such as good nutrition in childhood, low levels of smoking, access to healthcare, and also a willingness in the country to take up new medical knowledge. Among 65-year-old women in 2030, they estimated that South Koreans would live the longest, another 28 years.
Women have a higher life expectancy than men.
The next step of their research will be to extend their model to specific diseases as well as to all countries to provide more accurate predictions of life expectancy globally.
"In particular, we will need to both strengthen our health and social care systems and to establish alternative models of care such as technology-assisted home care", Ezzati said.
