Despite their innocent beginning, jigsaw puzzles, invented in the late 18th century by London mapmaker John Spilsbury, have endured two hundred and fifty years of consumer acceptance as a pastime not entirely anticipated by their inventor. Today puzzles come in multiple piece counts from as few as 10 enormous pieces for young children to assemble on the floor up to 20000 pieces for the most avid puzzle hobbyist that can take up to a year to complete.

Puzzles nowadays are no longer made of wood but of high density cardboard and are die stamped in a massive press to ensure a precision cut and consistent quality. In Spilsburys day they would have been made of hand painted wooden boards which were then cut into pieces with a jigsaw. World maps would have been painted on the board to be put together again in the classroom.

Color and shape are the most obvious clues to where a piece goes into the puzzle. This requires both manual dexterity as well as the ability to recognize complementary shapes and surrounding colors. For those whose cognitive powers are not as acute as they once were, it is obvious that jigsaw puzzles are a benefit to hand eye coordination as well as a mental exercise

Obviously there are many ways to stimulate the brain such as reading, crosswords or playing mind teasers such as Sudoku. Card games have the added benefit of socialization as well as deductive reasoning. It has been recently brought to light that physical exercise and diet rather than mental feats alone will help prevent the onset of dementia.

In order to allow seniors an easier option you can now find 500 piece puzzles the same overall size as a 1000 piece puzzle. Completing a puzzle instills a sense of accomplishment and satisfaction requiring the individual to observe, think about and finally execute a set of skills unique to puzzle making. Puzzles can be either solitary pursuits or family activities. As therapy they can be made up in groups with each individual assigned as specific task such as assembling the same color or straight edges.

Learning, consolidation, storage and recall are the four components of memory. Without recall the viability of other three functions cannot easily be observed. All four occur in a specific sequence and the ability to learn depends on the linear flow of information. Many activities (including puzzle making) will stimulate each of the functions. Competitive puzzle hobbyists regularly assemble a 1000 piece puzzle in about an hour. A seniors ability to deny the loss of mental dexterity will be enhanced by practicing a similar skill set.

As an attempt to address the problems of the aging brain, clinical studies and chemical discoveries as well as gene therapies appear reassuring and may even offer treatment today. Prior intervention requiring only the mildest but repeated stimulation such as discussed above is preferable to medical intervention. Diet, exercise and mental activity are the sure ways to provide stimulating challenges as well as pleasurable activities whose benefits could last decades.

We do not count our limbs or physical parts of our bodies as ourselves. The mind though is where we as individuals reside; the loss of which presents the greatest fear. Unassuming exercises such as jigsaw puzzles may help prolong a healthy mind and enhance the pleasure of life.
