Tosh! Thousands more people die in winter, not from cold, probably because they're stupid enough to see NHS doctors. They don't actually die of cold in a country where uninsulated old houses rarely even form ice on the inside of the windows these days. Even that isn't harmful; you should try it, it might make you realise you are much less fragile than you believe. In mentioning the architecture I was merely referencing that Britain having less-insulated houses than some countries is not some moral failing but an historical accident - but if I could trade all modern houses for beautiful ones I would do so in an instant. Even without heating they do not get cold enough in winter to kill you; if you transplanted them to Poland they would, of course, but we don't do that.
