Well, Spain has a very good universal health care system, which by the way places an emphasis on prevention, and is universally liked for the quality of life (work to live, not live to work), people are super social, weather is generally very good, good food is a religion, people walk, etc… so we could infer some things from this.
Hawaii, from what I remember (two decades ago) had a bit of that vibe. A lot of obesity, though.
