I remember in the 60's when i was a child, myself and my brother sleeping in the same bed as mum and dad as it was so cold at night, as the airing cupboard with the hot tank was in mum and dads room, there was also ice on the windows inside, and i remember playing in my room each morning in the winter with the ice formations quite a long way up the glass. one winter, (someone else whos older than me will probably tell you the year, but it was in the 60's) it was supposed to be the coldest winter for years, i remember the washing my mum had put out on the line, freezing stiff like cardboard, and she bought it indoors in big chunks to thaw out ! we used to have parrafin heaters all round the house, mum regularly spilled the parrafin on the kitchen floor when she re filled them. very stinky stuff.
