A lack of elementary hygiene is the extremely harmful habit to leave shopping bags (plastic bags, etc.) directly on the ground when being outside your home. On the same surface on which you place your bags there have been once droppings of animals and humans. Exactly in this environment stand ready to attach to a carrier the spores of germs (bacteria, viruses), other disease-causing organisms (ticks) and thousands of other invisible pathogens. When I visit public toilets I see that at least 3 out of 5 people leave their shopping bags directly on its floor! Once they get home they put those same bags with purchases on the floor where their child crawls and collects with its bare hands and mouth the street and toilets' filthiness, directly on the table where they use to meal, directly on the beds, sofas and chairs where they sit and wallow in dirt. If you could imagine the colossal invisible pathogenic filth you bring into your house, you would be terrified! Some people believe that some dirt is not detrimental because it helps their immunity. Is that so?
