As you get older, it becomes more and more vital to keep your brain regularly exercised. Science has recently confirmed that brainpower works in much the same way as muscle power - if you work it, it gets stronger, and if you ignore it, it gets weaker. This is known as brain plasticity. It's of particular importance to people who might be at risk of developing Alzheimer's disease. Several recent studies have shown that mental exercise is a key component in preventing mental decline, even in cases where the brain is actually being attacked. Puzzles offer a vital opportunity to keep the mind lean, fit and functioning properly.
