We live our life in an integrated way. You see you do eat carbohydrates and then eat proteins - rather you eat different dishes which in turn provide your body with different nutrients. Similarly, we do not use a car using math or physics separately - rather all the concepts of physics, senses, math, maps and directions and human coexistence come into play while we drive from one place to another. When we communicate we do not work with different grammar rules separately, rather we just talk or read or write.
So we all live an integrated or wholesome life.
