Gallup-Healthways asked more than 170,000 workers a series of 55 questions covering physical and emotional health, life evaluation and workplace environment.

Gallup assigned a score between 0 to 100 to each of 14 major professional categories, with 100 representing ideal well-being.

According to the 2012 Gallup-Healthways Well-Being Index, physicians have the highest level of well-being of any major profession.

Here are the most satisfied professions:

1. Physician...  Job types: Internist, obstetrician, anesthesiologist

· Well-being index score: 78.0

· Obesity: 86.0 percent

· Percent with health insurance: 96.7 percent

· Percent satisfied with job: 95.5 percent

Physicians were the most likely professionals to be described as "thriving." They were also less likely than any other workers to have felt sad or angry in the past day and the most likely to have the energy needed to be productive. Physicians are also exceptionally well-paid. Primary care physicians earned more than $200,000, while those with medical specialties made more than $350,000.

Teachers had higher self-evaluations of their lives than workers in every other occupation beside physicians. Almost 70 percent of teachers qualify as "thriving" based on their current and future quality of life. Teachers were also the most likely to report they smiled or laughed, experienced enjoyment or happiness within the past day. More than 64 percent ate at least five servings of fruits and vegetables at least four days a week, second only to nurses and just under 6 percent smoked. Average pay for "education, training and library occupations" was just over $45,000.
