People in Italy are apparently really, really healthy.
Scoring was based on a few things: life expectancy, causes of death and common health risks like smoking and high blood pressure.
But another factor behind Italy's high rank could be its people's access to health care.
Italy's health care system is universal; it covers the cost of many medications and has a lot of doctors.
Other countries that top Bloomberg's list are more or less the same; Iceland, Switzerland, Singapore and Australia all have universal coverage.
The U.S., however, came in at No. 34. The U.S. also doesn't have a universal health care system, but it's one of the world's most overweight nations due to poor diet and lack of activity.
