After a stroke we can re-learn how to talk, because by practicing we can establish different pathways in the brain, circumnavigating the damaged part.

It used to be thought that you stopped making new neural connections in your youth and from then on your brain was fixed and it was downhill all the way. But in fact as we know from our own experience we can keep on learning and learning means changing our brain on a physical level.

As we get older it is our short term memory that fades rather than our long term memory. Perhaps we have evolved like this so that we are able to tell the younger generation about the stories and experiences that have formed us which may be important to subsequent generations if they are to thrive.I worry though, about what might happen to our minds if most of the stories we hear are about greed, war, and atrocity

We don't have to have suffered brain damage to take advantage of the plastic nature of our brains.

The extreme of flexibility is chaos and the extreme of being structured is rigid and staying sane, or indeed using your creativity, is about being aware of these extremes and steering yourself to areas where you work best which usually tend to be more in the middle than at either extreme edge.

Beginning a new habit, or ending an old one can feel like letting go of a rope that swings a mile above the ground. So we feel reluctant to let go, after all, we've survived so far doing what we've done, why risk it.

If we are not using our brains' capacity for challenge it feels to me as though it atrophies like an unused muscle.
