Default Physical decline caused by slow decay of brain's myelin

Terry got me to reading The Talent Code and I'm very much enjoying it... except the part about how my myelin is breaking down rather than being built up! The point of the book is that talent is developed through targeted deep practice which develops neural pathways that are kind of reinforced by building layers of myelin around them to cause them to function better. We aren't born with talents, we learn them but, the older you get, the harder it is to learn them because your brain starts degenerating.

The myelination of brain circuits follows an inverted U-shaped trajectory, peaking in middle age. Bartzokis and others have long argued that brain aging may be primarily related to the process of myelin breakdown.

"Studies have shown us that as we age, myelin breakdown and repair is continually occurring over the brain's entire 'neural network,'" said Bartzokis, who is also a member of UCLA's Ahmanson–Lovelace Brain Mapping Center and the UCLA Laboratory of Neuro Imaging. "But in older age, we begin losing the repair battle. That means the average performance of the networks gradually declines with age at an accelerating rate."

Significantly, the research suggests that the myelin breakdown process should also reduce all other brain functions for which performance speed is dependent on higher AP frequencies, including memory; it also supports the suggestion that myelin breakdown is a biological process of aging underlying the erosion of physical skills and cognitive decline, including the onset of such age-driven disorders as Alzheimer's disease.

There is, however, some good news, according to Bartzokis.

"Since in healthy individuals brain myelin breakdown begins to occur in middle age, there is a decades-long period during which therapeutic interventions could alter the course of brain aging and possibly delay age-driven degenerative brain disorders such as Alzheimer's," he said. "Non-invasive, serial evaluations of myelin integrity could be used to monitor the effects of new and current treatments that may slow the process of myelin breakdown as early as midlife."


So, the lesson is, if you're under 40, FOCUS on what you want to be good/great at, such as swimming, and find ways to engage in deep practice such as TI techniques.

If you're OVER 40, you're going to have to work even harder to get there... but NEVER GIVE UP!!!
