Keep reading and doing those puzzles as you get older.
In fact, if you are younger, and don't do puzzles – start now and keep doing them … it's good for your brain –
According to a study:
Doing puzzles and reading books have been linked with a decreased risk of Alzheimer's disease, and a new study may explain why — it reduces the accumulation of harmful proteins in the brain.
I've always believed that games play the same role – they keep our brains active. And they provide, what I found, were some therapeutic results for people of many ages.
Of course I do have a bias.
I am, and have been, a big game player. I started out with pinball, moved on to amusement park arcades, video games and now computer games.
Just ask my son who played his video games more – him or me? 
I grew up with crossword puzzles and still do them. And the same with reading. Guess now I am glad I did so much of what others tended to call a "waste of time."
Do you play games? Do puzzles?
Have some favorites to share? Thanks……
