Why all the crossword puzzles?
Even old people who hate crosswords work them.
A while back, the notion got traction that if you used your brain a lot, it would stave off gooey crud in there, Alzheimer's, etc.
Gooey crud—yes, that’s a term of art.
An NIH study done in 2009 showed that a third of people don’t experience cognitive decline as they age.
In fact, deductive reasoning, general knowledge and vocab tend to get better.
“Your brain doesn’t know how old you are,” one doctor says, “and doesn’t care.”
Some people do theorize that you can build op a cognitive reserve, extra brain networks, by a lifetime of stimulating experiences.
One way to do this is to not quit working.
It also helps to keep your heart functioning well. Eat fish, nuts, and poultry and watch the red meat and dairy.
Or the opposite. There is a study for everything.
Studying those studies might be good for you, though.
Scientists also recommend quieting the mind for part of the day and have a lot of friends.
Sounds OK. I am not big on the crosswords, though.
