Whether we like it or not, we were not designed to be fearless. Fear is an emotional response connected to a basic need we all have – to feel safe. In the evolution of the human brain, this had been encoded for a very good reason. Our fear response is designed to trigger an action from us. If it’s a lion, we run. If we were to convince ourselves that we should not show fear and stand our ground, the stand we take is probably going to be immaterial to a starving lion. His fear that you may also be a threat, would most certainly be overridden by his fear of starving to death. Human beings are in any event rather defenceless without our modern weapons.
