Indeed, This is why we all grow more skeptical to "everything" which in turn actually leads some people to disregard pretty pure science, because when you start to have disbelief in the system, then it is also easy to disregard what helps us live longer, use resources more efficient, and actually enables the western situation where we have time to question everything. And the knowledge that it all can be wrong/a mistake.

I am sorry for a late and clumsy response, but I hope you get the meaning of what I am trying to express.
