Although aggression appears easy to recognise, defining it proves difficult. The difficulty appears to lie in distinguishing between acceptable aggressive behaviour which can occur when individuals are angry or frustrated, and violence, which involves the use of physical force and inflicts damage or injury to a person or property.
Aggressive behavior can cause physical or emotional harm to others. It may range from verbal abuse to physical abuse. Mental health conditions and brain damage can contribute to aggressive behavior. Occasional aggressive outbursts are common and even normal. Aggressive behavior is a problem when it brings harm to others or becomes a frequent, regular problem.
There are many ways to curb it though. If one sticks to the books, they can significantly reduce this problem and pose as a better human being.
