What noises get your attention?
The soft and subtle sounds that herald something satisfying? Text message notifications? A match being lit? A can of drink being opened?
Or the loud, intrusive and abrasive sounds that alert us to something awful? The piercing shriek of an ambulance siren? Your car’s graunching complaints when you fumble a gear change? The shrill whistle of a descending missile? The cruel insistence of your alarm clock?
The sounds that really get our attention are those that warn us something is wrong. An evolutionary legacy. We must either run toward – to save others – or away – to save ourselves.
