It's official and it's something we have known a long time.
The fourth estate, the defenders of democracy - yes, us journalists - drink more coffee than anyone else.
According to a survey of 10000 professionals conducted by PR company Pressat, journalists drink at least four cups of coffee a day on average. Police officers and teachers were the professions that most closely competed with journalists' coffee addiction.
In the survey, 70% of all respondents said their working ability would be affected without a mug of Joe. The survey also found that men drank more coffee than women, but only by a fraction of 5%.
Pressat said: "The highest consumers, sinking over four cups daily, were those with stressful careers."
University of South Carolina researchers recommended that people should not drink more than 200mg of caffeine daily - about two mugs or four cups of coffee.
Overindulgence carries a host of health risks, from strokes to heightened anxiety.
Other coffee-prone workers are plumbers, trade workers, nurses, and company executives.
