I think we've suffered so much with covid partly because we are so clean. We are supposed to be around dirt etc to build our immune systems. Especially children. Looking back over generations when people would be out scrubbing their front steps then yes we are less hygienic now, mainly due to laziness
That’s an interesting theory, considering covid is a virus spread by microscopic droplets. The only way to avoid it is by practicing impeccable hygiene and avoiding close contact. And of course building up immunity via a specific vaccine or contracting the disease itself, so your immune system can (hopefully) fight it off.
Do you truly think the pandemic was a result of people being too clean (and not having immunity to a very specific molecule which mutated and evolved to bypass even the strongest immune system?) That being exposed to more dirt would have allowed our bodies to replicate that specific spike protein so we didn’t get ill with it?
I don’t agree all dirt is good. Sure kids need exposure to some dirt and minor illnesses like colds, but they don’t need exposure to say salmonella or tetanus or toxoplasmosis or a number of other serious pathogens, viruses and bacteria.
People die from infections caused by bacteria and virus exposure all the time. Take cellulitis for example, a common skin infection capable of causing fatal sepsis. Or Lyme disease, spread by a tick bite that may go unnoticed until the damage is done.
Not scrubbing the front door step is hardly going to cause illness (unless you plan to eat off it or lick it). Maybe people stopped scrubbing doorsteps when more women joined the workforce instead of being housewives?
We need to build up immunity yes and nobody’s saying we should live in a sterile environment. But basic hygiene like washing hands when you come home/after the loo/before food prep, and not sneezing or spluttering near other people or sharing cups/toothbrushes is sensible. As is keeping kitchens and bathrooms clean, not letting rooms get damp and mouldy and staying away from others when ill.
