Many of us enjoy a cup of coffee in the morning -- but depending on your job, you may be more likely keep a pot brewing all day long.

In a survey of almost 5,000 US workers, Dunkin’ Donuts and CareerBuilder found our professions, age, and even the region in which we live can influence how much java we drink every day.

For example, about half of the survey respondents in the Northeast admitting to needing coffee while on the job, and younger workers -- those between 18 and 24 -- said drinking coffee gives them the chance to network with other employees, thus helping their careers.

And which workers are most likely to say they need coffee to get through the workday? Scientists and lab technicians took the top spot, with marketing and public relations people taking runner-up honors. Education administrators, writers and editors, and healthcare administrators also ranked among the most caffeinated professionals in the country.
