There's a new challenge in France: Whoever turns on the heating first loses The French are competing on social media to see who can last longer without batteries. They sleep in hats, wear three sweaters and wrap themselves in blankets. Especially persistent ones are going to last until December. But behind the cheerful flash mob hides a completely sad reality. 72% of households in France are forced to limit their heating due to the high cost of energy. And 35% experience cold in their own apartments. Pensioners admit that they sleep in their clothes because they are afraid of the electricity and gas bills.
