patthu and hygiene hype

Just now saw the bunch on some AgraHARAM 10 echil nuisance and nonsense in my opinion.

By logical extension chemically sodium chloride with some carbohydrates and proteins runs in our blood at a normal boiling point of 98.4 degree which gives energy by which we are able to touch even any  vessel. 

So, the moment we touch anything it is already a patthu ( going by salt, boiling temperature , cooked internally in our body) if we want to add our own spice lick it to add echil or any product th​​at we buy from the chair or soap in manufacturing cycle may have come into contact of echil or saliva of some human or insect.

Now, debate because if pathhu was that important concept it should have predated the invention of cooking devices.
