Habits are behaviors that we tend to repeat on a regular basis. Our behaviors are controlled by our frontal lobes of the cerebral cortex. There is a neurological law the is called the Law of Facilitation. What it basically says is that the more times a neuron pathway is used, the easier and faster it will conduct an impulse along that same path. That's how we learn to ride a bicycle, or swim, or any other physical activity. It also explains why we tend to have certain habits that are particular to us individually. because we all do different things and develop different habits.
