Media types are officially the heaviest drinkers in the country, the Depatment of Health says so.
Teachers are the most likely to moderate their drinking.
As a good analyst who doesn't just present the data, I've come up with two hypotheses...
(a) When you're nursing a hangover, it's more palateable to face a Marketing Director than a class of 12 year olds.
(b) With twenty odd days holiday a year rather than every third month off, us media types really need that drink.
Further research is needed into this important question. If you need me, I'll be in the pub.
