The easiest way to be smart is to be born with clever genes. Some are lucky, but the rest of us have to make an effort to be smart. There are several ways, so the experts tell us. Last week I mentioned some of the foods that are supposed to be good for the brain.

We all know physical exercise is good for our general health, but did you know that physical exercise is also good for your brain? Even walking sedately for half an hour, three times a week, can improve learning, concentration and reasoning.

Exercise is a natural part of life. Now we’ve become a sedentary society, spending so much time sitting in front of the computer or TV, we have to consciously include physical workouts into our daily routine. Biologically, exercise was part of survival, in the form of hunting and gathering or raising livestock and growing food.

Historically, it was built into daily life, as regular hours of physical work or soldiering. What is now considered a form of exercise -- walking -- was originally a form of transportation, the old shank’s pony. We believe that growing old means our brains inevitably become feeble – yet when this happens, it’s probably because we’re not as physically active as we once were.

Experts tell us exercise improves the heart's ability to pump blood more effectively, and increases the blood's oxygen-carrying capacity. It’s thought one of the reasons why the elderly -- especially those with coronary artery disease or hypertension -- tend to suffer some degree of cognitive decline is partly due to a reduction in blood flow to the brain.

So don’t be a couch potato or an office chair potato -- get out of your chair and get that blood pumping!


Happy puzzling!
