I'm old and diabetic and some other things.As a kid lived with Gran Ma most summers and other times.No lectricity and no pumbing.Water was from a well or springs up the hills.I drank from the same tin dipper as others...and none ever had a cold or other illness. generally.Nothing quit as refreshing as a cool drink of water from that tin dipper on a hot summer day. Stepped on a nail and it went all the way through. Soaked in in coal erl and next day a bit sore but didn't slow me down. Dirt: I was always in it,the garden or walking the woods and the road to Thoma's store to buy more.22s or town and bathing in the creek was normal and preferred in summer.
However there is more than one cemetery in the mountains of relatives who died in their 20s.Average age seemed to be about 24. I have administered more than one Whole Life policy that was paid up at age 35. Average age at death was in the forties!That was the 19th and first part of the 20tth century.In that very rural area they died and the pathogens eventually died out with them. N one new moved into thee area until the late sixties.
Diseases were aplenty.The reason Mom's family and many rural families survived the Spanish flu and countless other diseases was that no one moved into the area until late 60s bringing diseases with them. And Mom's family back before her Ancestors,native Americans washed every day, in the clean creeks and rivers and ponds, or with hide buckets of water.
And they did not use animal or human manure despite whoever else may have.
The contagions breed and are nourished in rich soils, the richer the better.
Today, when the winds come from the southwest ll the way from the fields in La, Tx, Miss and South Alabama, our home gets dirty from it and people get sick at those times.I grow tired of washing the home down. I have even been caught in a mud rain just at the foot off where our drive is now.
All those fertilizers, herbicides and poisons, bacteria and germs and soot from burning fields in the top layers of soil that are blown directly onto our front porch and others are loaded with them.
Dirt, that is clean dirt so to speak had the potential to give us germs and bacteria but a lot less than today.
Keeping clean, including washing our hands, when handling the sewer hoses etc is something we would have done back then if we had such things as RVs. Inviting disease is not macho by not washing our hands or wearing gloves,or even removing our shoes when we enter our RVs. Dirt now had a higher potential to contain pathogens. And someone who had the flu or worse, and used the dump station before us,has left some time bombs for us, to the degree they were or not clean, and one of the reasons we choose RV parks with full hookups. And...one thing to consider is that more germs are spread by aerosols germs lingering, in the air blown off the stuff on the ground...and at septic dumps.
Ass an example the Spanish flue.
