A bit of cold and fresh air in a house never did anyone too much harm. Now we have asthma, continual sniffling and snorting, coughs, infections, cold sores, big bulging bellies, etc, etc, etc. People demand more insulation, more heat, walk around with nothing on them and blame everything on the planet being banjaxed or about to blow itself up. Maybe, just maybe what's needed is for the so called experts in some field to come out and inform us that nature will take of itself and we'll all be ok. Animals don't need inhalers, statins, cholesterol drinks or too much mollycoddling, yet they survive and feed the planet but there's some who want that stopped too. We need to get a grip of ourselves and get out more into the fresh air
