Yes I remember those days:
Single pane windows that ran wet with condensation.
Black mould in my bedroom ceiling and around the window frames
Lead pipes that froze in winter so the bath and sink water couldn't run down and you could remove the cork and it would sit there. For days and days.
One heater on in the living room and almost crying from the cold if you had go up to bed, get up in the night to go bathroom or get up in the the morning.
Having to bathe in a big bowl in front of the fire. Because of the cold.
The gas cannister running out of the portable fire and my dad breaking into the meter to recycle the 50p, because we'd have to use the mains gas fire, until the cannister guy came by again.
Getting chilblains, developing asthma at 9 years old, cold air further inflaming my lungs. Shivering at night. Having to sleep in my parents bed with my brother to keep warm.
It's unacceptable that we're even saying we should jump back to this. Profits are being made and the poor are actively being asked to further reduce their standard of living by decades. Half a century at least.
