This is the book I have been looking for over many years. There are many books explaining ways to keep your brain 'fit' well into old age, but if you explore their research and other support, they most often fail to meet a high standard of independent research or depth of analysis.
Soft-Wired is an excellent book supported by decades of rigorous scientific testing and testimonials of people who have greatly benefited from the brain exercises available in the PositScience website. I have been using the PositScience exercises for 3 months and notice marked improvements in listening ability, short term memory, sharper reactions etc. This book accompanies the exercises perfectly in that you get to fully understand how they 'soft-wire your brain to develop your full potential. The book is very well written and easy for a non-scientific mind to follow.
If you have ever witnessed the effects of declining brain function in those close to you, Dr Merzenich's book will be an inspiration to explore this exciting new science and enjoy the later years with a youthful brain.
