On the lighter, yet still important, side of learing and also something this old lady struggles with from time to time (focus, concentration, alertness), I thougt I would share with the group my wandering and seeking discoveries.  Pay special attention to item No. 2

A few excerpts  from the WebMD Slideshow:

BRAIN FOODS THAT HELP YOU CONCENTRATE

http://www.webmd.com/add-adhd/slideshow-brain-foods-that-help-you-concentrate

1.  Fish Really is Brain Food

A protein source associated with a great brain boost is fish — rich in omega 3 fatty acids, essential for brain function and development. These healthy fats have amazing brain power: higher dietary omega 3 fatty acids are linked to lower dementia and stroke risks; slower mental decline; and may play a vital role in enhancing memory, especially as we get older.  For brain and heart health, eat two servings of fish weekly.

2.  Add a Daily Dose of Nuts and Chocolate

Nuts and seeds are good sources of the antioxidant vitamin E, which is associated with less cognitive decline as you age. Dark chocolate also has powerful antioxidant properties, and contains natural stimulants like caffeine, which can enhance focus and concentration. Enjoy up to an ounce a day of nuts and dark chocolate to provide all the benefits you need without excess calories, fat, or sugar.

3.  Add Avocados and Whole Grains

Every organ in the body depends on blood flow, especially the heart and brain. Eating whole grains and fruits like avocados can reduce the risk of cardiovascular disease and enhance blood flow, offering a simple, tasty way to fire up brain cells. Whole grains, like popcorn and whole wheat, also contribute dietary fiber and vitamin E, while avocados have fat — but a good-for-you, monounsaturated fat that contributes to healthy blood flow.

4.  Blueberries Are Super Nutritious

Research in animals shows that blueberries help protect the brain from oxidative stress and may reduce the effects of age-related conditions such as Alzheimer’s disease or dementia. Studies also show that diets rich in blueberries significantly improved both the learning capacity and motor skills of aging rats, making them mentally equivalent to much younger rats.
