Lack of influence

Bone Remodeling

Bone remodeling (or bone metabolism) is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation). These processes also control the reshaping or replacement of bone following injuries like fractures but also micro-damage, which occurs during normal activity. Remodeling responds also to functional demands of the mechanical loading.
In the first year of life, almost 100% of the skeleton is replaced. In adults, remodeling proceeds at about 10% per year.[1]
An imbalance in the regulation of bone remodeling's two sub-processes, bone resorption and bone formation, results in many metabolic bone diseases, such as osteoporosis.[2]

The bone remodeling process goes on whether I want it to or not. I can influence it by exercising or lack thereof but I cannot direct the osteoclasts or osteoblasts individual activity. They respond to clues in the environment. It is interesting to me that we are always building and destroying bone.

Brain remodeling

Neuroplasticity, also known as brain plasticity, is an umbrella term that encompasses both synaptic plasticity and non-synaptic plasticity—it refers to changes in neural pathways and synapses which are due to changes in behavior, environment and neural processes, as well as changes resulting from bodily injury.[1] Neuroplasticity has replaced the formerly-held position that the brain is a physiologically static organ, and explores how - and in which ways - the brain changes throughout life.[2]

Seeing and relating to the left side of peoples face especially connecting with my left eye to their left eye seems to be changing my access to my left head/neck/tongue/throat. A great deal of the process feels to be not under my control similar to the bone remodeling. There may be a degree of influence but I am for a large part unable to control the rate of change.
