It looks as if it is now time to cash in on the Carbon Footprint Fashion or the high cost of fuel and put a plan to the nation. I have an idea, - well, perhaps more a pie in the sky at this stage.
We do not have rules and regulations in our house but I often advised the kids that, if it gets a bit cold, we should put on a pullover first, then turn up the central heating only if it is still cold. This is what people did long ago; they didn't have central heating they wore waistcoats, jackets or gowns in the house to keep warm. Now-a-days everyone goes around the house in shirtsleeves and pumps up the heat to keep warm! Think of the money and energy they would save if they wore a pullover.
I am not a sheep farmer but I am sure the wool trade and Dept. of Energy could come up with a catchy phrase like "Ware a woolly jumper" or something and get the population of Britain to keep warm save fuel and reduce their Carbon Footprint (It doesn't matter if you believe in Carbon Footprinting or not) and most importantly of all - save fuel bills! by wearing a woollen pullover.
The next thing to get over is how much warmer, (or cooler), less sweaty, and more comfortable a woollen pullover is compared with an acrylic one - wool breaths -. Surely the Government would help promote this fuel saving and cost saving common sense way to dress indoors. If it took off it would do wonders for the wool trade.
When in Rome, do as the Romans do.
