While riding a bicycle I couldn’t give you the theory behind what makes a bicycle work in any type of scientific detail. I’d crash. Doing and thinking are separate things.
Doers do. Thinkers think. You can do both if you try, just not at the same time.
When you do something because human nature tells you to do, it or culture dictates that you do it, or habit compels you to do it, just do it and think about why you do it later.
If the mother must understand the science behind her maternal instinct before springing into action, her baby would be dead. Do, do, do and examine why later.
