Accessible and well organised, this book covers the main areas of concern most of us have as we age - how inevitable is deterioration in brain function, how do we keep mentally fit, to what extent is our brain function determined by genetics and are there advantages to an ageing brain?
The author introduces us to some of the language and domains of neurological research and backs up his arguments with references so further exploration is possible. Each chapter concluded with a useful summary of the conclusions.
What I take away from this book is that older brains (from 65+ years) hold their ground in knowledge and vocabulary. They also have some advantage in resolving complex 'wicked' problems, especially those involving human interactions (an association with wisdom). While some parts of the brain inevitably deteriorate with age, we develop other to compensate.
Aged brains are, however, slower than younger brains, less able to distinguish relevant from irrelevant data and less able to retain new information.
There are ways of slowly the decline - most well known. The author examines evidence and comes down endorsing the importance of remaining physically active, socially engaged, mentally stimulated, spiritually engaged and eating moderately.
For me personally, I will try to drink more water and exercise more.
The book has also proved a good discussion point with young people - there are many implications that would make it interesting to read an equivalent volume " the youthful brain!
