The US is on a downward slide , in terms of life expectancies.
According to latest figures compiled by the Census Bureau, the average life expectancy of Americans now stands at 77.9 years, ranking 42nd in the world, down from 11th two decades ago.
Japan, Singapore, most of Europe and even Jordan have longer life expectancy than the US.
According to some experts, the slipping of life expectancy ranking could be attributed to the fact that large numbers of Americans, as much as 45 million, do not have health insurance.
Other factors include widespread obesity, racial disparities and relatively high infant mortality rates.
