It's common knowledge that some countries have higher life expectancies(预期寿命)than others，but the city you live in can also affect your health.
Some cities are hard on their citizens.In places with poor city planning—Lagos was called out recently by the Economist Intelligence Unit—public spaces are few and far between，making outdoor activities hard.Lack of infrastructure(基础设施)jams the streets with cars and the air with pollutants，and people work long hours for little money.
These are just some of the factors concluded by Spotahome，a rental agency.They've analyzed data from a range of sources，including the World Health Organization，TripAdvisor and the CIA World Factbook to score each city on health，gym availability and quality，life expectancy，obesity(肥胖)，green space and other elements to work out a list of the world's healthiest cities.
The list is certainly Eurocentric but continuous sunshine is seen as a positive thing，even if it may be more of a disadvantage in other regions.But it does go some way towards suggesting which cities are getting it right in providing a good life for their inhabitants.
It may not be surprising to learn that most of the healthiest cities are in northern Europe，known for its peoplefirst approach to city planning.Australia and Canada also do well—but Alaska，the first U．S.city is only in 34th place.The U．K.doesn't fare too well either—its only city in the top 50 list is London，in 40th.
Whether you're planning a wholesome holiday，or simply wondering what your city can do better，this list of the 50 healthiest cities will give you pause for thought.Here are the attractive，healthyeating，cleanaired cities that are getting it right.
