It is a powerful video, yet it only speaks to half the reality of being human. You see, a wild animal, that is prey or territorial, has reason to fear whatever threatens survival or breeding/feeding advantages. Humans, and the video you posted illustrates this point well, fear needlessly for all kinds of irrational reasons. This is neurosis (anxiety, avoidance behaviors and illogical thinking) and if left unchecked, can lead to psychosis (defensive/aggressive behaviors, violence and cruelty).
For some strange reason, we humans have not evolved our psyche in pace with the survival advantages we have gained that really should give us greater peace of mind and sense of security. Our greatest threats come from our own species. We fear each other more than any other species. We compete within our social structures, even though we have the option to restructure so that competition is made obsolete.
Being human, we call ourselves Homo Sapiens, which means ‘Thinking Man’, but fear flies in the face of such a claim. Fear is instinctive, reactive, visceral and emotional. Strategically analyzing and devising an approach to lead one out of fearful situations is what a thinking human does. Fleeing from threat is what an inferior or weak animal does. Defending possessions is what any animal will attempt to do when it perceives offensive threat. Fear is an instinct that all animals possess.
We aint human without (rationalising, understanding and then eradicating) fear... :57:
