I say a murder is abstract. You pull the trigger and after that you do not understand anything that happens.
Trigger
Patients who trust their doctors and have a psychological expectation of getting better could trigger a reaction in their body.
Climate change, in some regions, has aggravated conflict over scarce land, and could well trigger large-scale migration in the decades ahead. And rising sea levels put at risk the very survival of all small island states. These and other implications for peace and security have implications for the United Nations itself.
Ideas pull the trigger, but instinct loads the gun.
