From 41 - 50. Next 10 ways to boost your brainpower

41. Sing. When you are alone in your car, try singing about something you are working on. This taps into and exercises your right brain. Have you ever noticed how it is easier to rhyme when you sing than when you just speak or write? This is because the right brain is better at pattern recognition. By doing this brain exercise regularly you can train yourself to tap into the power of the right brain. This will make you a more effective problem-solver. If you doubt the distinction between the hemispheres of the brain, look at how stutterers can stop stuttering as soon as they start singing. Try it.

42. Nuts. University students in Brazil and other South American countries often eat several Brazil nuts before an exam, believing they are good for their mental power. The evidence is starting to confirm this. Other nuts that have minerals and amino acids that are beneficial to the brain include almonds and walnuts.

43. Olive oil. High in mono-unsaturated fat, olive oil has been shown to improve memory. A cheaper alternative is canola oil, but this hasn't been studied much yet.

44. Vitamin supplements. In studies, children scored higher on tests when on a regimen of daily vitamin supplements. "Experts" will tell you that if you eat a balanced diet, you don't need supplements, which, given the culture here, is really just a sales pitch for vitamins, isn't it? Who eats a perfectly balanced diet?

45. Fiber. It isn't just what goes in, but what comes out that is important to brain function. Toxic build-up in the body and brain can cause "brain fog." People often report clearer thinking as one of the benefits of curing their constipation.

46. Self awareness. This may not seem important to brain power, but it is. When you know yourself better, you can avoid the usual effects of ego and emotion in your seemingly "rational" thinking. Or you can at least take it into account. Watch yourself, especially as you explain things or argue.

47. Motivate yourself. Motivation is as important to mental tasks as it is to any other. Learn a few simple techniques for self motivation.

48. Avoid too much stress. Neuropsychiastrist Richard Restak, M.D., form the George Washington University School of Medicine and Health Services, sums up the research thus: "Stress causes brain damage." Long term stress has repeated been shown to hurt the brain, not to mention the rest of the body. Learn a few stress reduction techniques if you get stressed out often.

49. Get educated. Scientists have known for a while that the less educated get alzheimer's more frequently. Education in any area seems to make the brain stronger.

50. Avoid too much fat. In laboratory studies, animals consistently learn slower when they are on a diet high in fat. Type of fat may make a difference, so you may want to stick to using olive oil and other non-saturated fats. Saturated fats have been shown to actually stunt the growth of brain cells.
