Truth

Does anyone person always tell the truth? Is it possible? Why so or why not? Its so easy fr peole to lie yet difficult to always be truthful. Why? Is it because we are surrounded by lies via our news and other sources of media so we figure might as well tell them what they want to hear. Would the world be better if everyone was honest or are there just some things that must be lied about? The truth can be powerful, and surprising and very real which is maybe why its often avoided.
