cleanliness has to do with population and life style - modern societies have a greater need for 'cleanliness' than a tribe living out in the jungle. Look at Japan with its dense population, cleanliness is extremely important. Theyre not germophobic, they have a great need for it.

imagine a tribe in a jungle - they live in a hut with only a thatched roof on top. they don't have to worry about poor air that modern homes have to worry about. the modern home has HORRIBLE air with too much dust, bacteria and the likes. the open hut has open circulation - air comes in air comes out. They dont have to worry about dusty stale air. who do you think develps allergies more? the tribal man? or the modern man??

in the modern home, people DO get sick becuase of the poor air inside of their home. and what do you get? modern air sanitizers................which might be counter productive.

the tribe is just that, a tribe of people. they all know eachother, live together and might even be all related. they share immune systems and germs. but its not like that in the modern society is it? we come into contact with total strangers every day, and many ARE carrying illnessess. the result? we get stomach viruses, flus, headaches and everything else so much more often then our tribal friends in the jungle.

so with that said

is there a big need to wash your hands before eating if you have been home all day? no.

is there a need to wash your hands before eating if you were outisde in mother nature all day? well that depends if you were playing with dog poop..

is there a need to wash your hands before eating if you were on the streets, in public places all day long? if youre not gonna wash your hands you might as eat off of a gasoline station toilet and lick the pavement clean. I for one think people in this scenario who dont wash their hands are dirty, smelly, and from what Ive noticed they have dirt caked under their nails too.......eeeww......

wash your hands you dirty monkey! the city streets are dirty nasty with diseases, illnesses, viruses and HARMFUL bacteria. The dirt on which tribes grow on, is clean!
