High risk areas like hands?
I've been suffering from an E.Coli for over two months. It has complicated itself into several parts of my body. I don't know where it came from, maybe the swimming pool water, or the wash room at the Ethiopian food restraint and I ate with my hands, maybe someplace else. It can take a few days to incubate.
It Knocked me out, dick to the dirt, for a several days severe fever and diaria, then in the next week as I thought I would be getting over it, milder, but debilitating symptoms persisted. It is supposed to run its course, but apparently it is a long course and the illness stripped a few gears.
A body certainly develops immunities from the environment. Years ago, I ate blood sausage with my Colombian friends on the streets in Bogota. They were fine. I got wiped out with colitis. The Native Americans died by the millions, when the Europeans introduced disease. So, I'll wash hands and veggies that I eat raw and buy in the markets from Mexico and other world sources.
The soil from my garden is a healthy issue.
The last three times that I have had amoxicillin for dental work, I've caught diseases shortly after and had long recovery and severity. Now, I'm on antibiotics to get rid of this E.Coli condition. All I can do is eat fermented foods and hope to recover and balance my biome. Maybe a fast might reset my gut, but that will have to wait. MAybe, I'll make some tea from my garden soil, eat grass like a dog.
As for people in hot climates wearing clothes, yup. Clothing obsession is a major problem as you say. Our bodies are adapted to live in sun. We're better off without clothes most days. But then there are the desert sand people.
North Africans, wear clothing. Mostly it is religion, tradition, control, status, identity and ignorance from never being naked. The Arabs are wearing thin clothing. But then there are those out in the sands in black blankets.There can be some insulation value, like a Russian wool cap in the sauna, but why do these nomads make it black, when that absorbs heat? Are they conserving water, moister? When in fever, a body chills and wants to be covered. One reason is to heat and kill bacteria. What are those guys thinking?
