A bear and a man come face to face: their reaction is ... IDENTICAL!
What would we do if we met face to face with a bear? The advices in this case are many (stay calm, do not run, do not show aggression) but nobody could save us from having a great fear. Often we do not realize, however, that wild animals think the same way, and often flee terrified in front of a being two meters tall, who speaks and who has no fur.
