Why households must not cook if there's a dead body inside the house. A good article must read

I have now learnt the importance of the following: 
*1.* Why bathrooms and toilets were *outside* our houses and not *inside*. 
*2.* Why we should not touch anything or anybody when we return from a barber shop or a funeral. You may return to normalcy *only* after having a bath as soon as you enter the house. 
*3.* Why footwears were kept outside the house and not inside. 
*4.* Why we needed to wash our hands and feet when we returned from school or after playing outside. 
*5.* a mandatory 10 days isolation/quarantine was required when there was a birth in the house or death in the family). 
*6.* Why households must not cook if there's a dead body inside the house. 
*7.* Why washing of clothes was done outside the house and not inside. 
*8.* Why it was mandatory to have bath before getting into the kitchen and cooking and eating food.
*9.* Why once you have had a bath, you were not supposed to physically touch those who were still to take bath. 

Our "western education" brainwashed us to view all these things as "orthodox" with no place to follow in our 'modern" world. But these are the things which are coming to our rescue now. Maintaining physical hygiene, social distance and cleanliness were laughed at, ridiculed, insulted, systematically.

Think how advanced our ancestors were and their knowledge of causative agents, sanitary practices and infection control . 

Time to go back to our roots.
