I want to cheer the headline, but how useful is this data when so many wildly different professions are lumped into the #2 occupation? Professional worker--lawyer, doctor, scientist, teacher, engineer, nurse, accountant, computer programmer, architect, investment banker, stock brokerage, marketing, musician, artist Is it really of any value to anyone to lump the "Overall well-being" of an artist, computer programmer, and investment banker into the same category?
