Working crossword puzzles has been shown to be a simple activity
that can help prevent or at least stave off some forms of mental
atrophy. It is a medical fact that as you grow old and/or cease
presenting yourself on a regular basis with mental and physical
challenges, your brain actually begins to lose gray matter and
synapse interconnections are lost. Working crossword puzzles
is a healthy mental exercise that helps increase your vocabulary
and improve cognitive skills. That is one reason I create a
crossword puzzle for RF Cafe visitors. Electronics magazines
of the last century regularly published theme-based crosswords,
like this one from a 1960 edition of Electronics World.
