An accident occurs because of having it to occur without the will to do so or in a way that it has happened without the thought of having to realize that you don't want it to happen after the event has been made. Risky behavior is a behavior of a human in which it could cause bad effects towards self and towards other people in which it could be a cause of something bad. An example of an accident is when you trip on a path because of the rock that you haven't even seen. Another example of risky behavior is when you try to fight towards other just to prove you're right even when you know that you're wrong, just to show them who is on top or the boss.
