Everything that we have been told is a Lie

I have found it strange now, for several decades, just how ignorant people can be.
What I mean is, when they accept virtually everything someone tells them. as the truth.
Yes, especially if it is aired on the major news networks.
I believe that we must learn to question everything, because there is no reason to jump on any and everything someone tells us, especially, when the information being shared involves our potential health and wellbeing, or livelihood.
