New research has finally offered up a potential answer to the question 'why am I in such a foul mood all the time?'
Yes, some bright spark has actually tried to put together a 50-point list of things that are guaranteed to throw you into a proper mard. So, this Monday - when else? - let's see what is really the reason that Britain is so pissed off all the time.
First off, sleeping badly. It's so simple, yet so infuriating. The study, which surveyed 2,000 adults to see what made them seethe, found poor sleep to be the main cause of ire in the UK today.
In fact, a lot of the big hitters are pretty predictable.
Stepping in dog shit is in at number two - rather aptly - while there are also appearances from things like feeling a bit under the weather, being late for an appointment, and having to drag your sorry arse out of a warm bed on a cold morning.
So far, so simple, right?
Things start to get a bit more abstract as you go down the list. For example, take people spoiling a TV show for you (number 38) or going on Facebook and realising how pointless is it (number 45).
This particular piece of indispensable research was performed by Phillips Hue smart lighting and OnePoll.com.
They found that while the average Briton spends just one hour and 52 minutes in a bad mood, just under half spend their whole day - from getting out of bed to getting back in - under a cloud.
That takes some serious effort.
Interestingly, they also discovered that six out of 10 Brits suffer from 'Winter Blues'.
A Phillips Hue spokesperson said: "Winter can be a dreary and difficult time - the weather is often cold and wet, we have no money and everyone is generally in a grump.
"This means many more things than usual can put us into a bad mood, something that's not helped by the dark mornings and evenings.
"Lighting not only effects visual conditions, it also influences our biological functions and emotions, while colour is thought to have a huge effect on our moods."
Who would have thought that research by a lighting company would have revealed lighting as a potential solution? The mind boggles.
However, there is a bit of science behind it. They also asked colour psychologist (yes, that's a thing) Karen Haller to produce a mood board with some suggestions to ensure that we see the right colour to keep us in a good frame of mind.
Haller explained: "Colour is not just a visual stimulus. Colour influences how we feel, think and behave.
"We respond to colour and the combination of colours in our environment throughout the day. We don't even realise we are doing it.
"We are typically only 20 percent conscious of the colour choices we make, from getting the colour of our morning cuppa just right to the colours we choose to wear, and which tube line to take."
That explains my predilection towards wearing black every single day of my life. However, it's incredibly difficult to step in dog shit if you're staring miserably at your feet.
Every cloud, eh?
