We live a very cosseted life in the West; we can, at the touch of a button, increase the temperature of our homes without a thought to the consequences.
Central heating is expensive in terms of using scarce resources, and environmental damage.
Many of us waste these, by running our homes at unnecessarily high temperatures.
The next time you are feeling cold, instead of reaching for the heating control panel, put a jumper on and eat a bowl of hot soup.
You will save money and the environment.
