Answer:
A habitual action is an action based on past learning. It is not the result of a conscience choice, but rather something a person does out of habit. Habitual actions are often called irrational actions because they don't come from reason, but instead, come from our "heart". Examples of habitual actions include: waving good morning to your neighbours, listening to the radio while you drive, etc... (you don't have to think about these actions or the consequences of them, you just do each of them out of habit).
