Before violence comes anger, and anger is caused by specific chemicals being released in the brain. It takes around 90 seconds for these chemicals to dissipate, and for feelings of anger and aggression to disappear.
Take:90 is a not-for-profit initiative supported by an alliance of public, private and third sector partners. It aims to address verbal and physical violence in society by encouraging people in stressful situations to take a moment before anger gets the better of them.
