Hong Kong is a surprise entry to the list. It’s infamous for air pollution, boosted by the more than 7 million people living in close proximity. But medical treatment has gotten better and people are generally very active. Many practice martial arts their entire lives, which helps with longevity, according to studies. People also prefer steamed food, as opposed to fried, and drink a lot of tea. Most of the protein Chinese consume is from plant sources.
