According to a news item, the UK is only in 24th position of the International League Table of 'happiness' (see http://news.bbc.co.uk/1/hi/world/africa/3157570.stm). This is put down to our 'long working hours' culture.
But could this culture have grown out of the gloomy weather, pretty much year round, but particularly between January and December? LOL!
Forget trips to the desert, the snow-capped mountains, wide-open plains etc.
The only thing this damp, grey, gloomy weather is good for is making mud!
No wonder we're good at being grumpy!
(P.S. at least Manchester United were disgraced yesterday in the FA Cup!!)
