Hearing that alarm go off first thing on Monday morning is totally depressing, almost as bad for morale as when we stopped getting carded at clubs. And having to drag your still-hung-over, overtired self through the day is no easy feat, either. So, what about the news that Tuesdays are even worse?

Yep, people are at their lowest on Tuesdays, according to a new study from the London School of Economics, where researchers monitored the moods of 22,000 people over a two-month period, using the iPhone app Mappiness.

George MacKerron, an academic in LSE's Department of Geography and Environment, told The Telegraph, "It seems plausible that on Monday the weekend has not quite worn off. By Tuesday they are well into the working week and the following weekend is not yet in sight."

Clearly these guys haven't yet discovered the power of the liquid lunch.
