I doubt it was healthier to live in the cold houses of our childhood. Many of them were damp as well as cold. My father's waiting - room resounded all winter to the coughs, sneezes and snuffles of patients with colds!
He saw a lot of bronchitis too, but all right some of the sufferers had been gassed in the first World War and weren't just suffering from cold rooms.
My sister's godmother had chillblains on her hands and feet from November till May, working as she did in a draper's shop that only had a very small open coal fire in the back shop and no heating in the shop itself - plus a communal W.C. in the close that was open (the close , not the communal amenity) to both the street and the back yard.
But a lot of people are not going to have a choice, are they?
Or rather, let me rephrase that. Of course, they have a choice - keep warm and bankrupt yourself paying the heating and electricity bills, or keep warm and eat the bare and cheapest minimum to stay alive, or turn down the heating, stop airing the rooms " to keep the heat in" - remember that phrase?
Bundle yourself up in layers and layers of clothing and remember to buy an old fashioned hot water bottle or three because you can't afford an electric blanket any more.
And try to enjoy re-visiting the conditions of your early childhood at a time of life where you can no longer run three times round the garden to warm yourself up!
