Answer
Explanation:
If you have a hammer that you want to use, everything begins to look a nail. It is just so that we alter our thinking by our perception following this process and it is sort of a self-fulfilling prophecy. If you smile at someone, they tend to smile back. If you grimace or frown, then you find others doing the same.
All this affects not only our brain but also our senses, facial expressions, body language and anticipation of such, our world-view. If you escalate an argument, it gets worse and if you de-escalate an argument things return to somewhere closer to the norm.
There are neurons throughout the body, so what you do affects your whole body, not just the thinking of your brain. Just so, stress from one source or another affects the heart and love preserves it.
Everyone has slightly different parts of the brain for its functions. In the case of traumatic brain injury or concussion, one part of your brain, all else being right, compensates for its loss in one part to another.
We live as a whole being, and the way in which we live our lives leads to a tendency in that same direction. If you are angry about something or hold grudges you will tend to become an angry old man or woman. If you are kind, then you will tend to think kindly and become a kind and gentle person.
