Jog your brain fit

Jogging, dancing, playing tennis and more is good for the brain because variation as well as intensity of physical activity helps to keep it fit whereas time spent active is less important.

This is the result of a study in nearly two thousand Dutch men and women aged forty-five to seventy. All have been asked extensively about their physical activities, and their memory, mental flexibility and speed of information processing have been assessed with a battery of various tests.

Those who performed best in these tests were most likely those who engaged in intensive activities and who did so in a number of different sports and leisure occupations. In contrast, the time spent on physical activities did not show a significant link to mental fitness in this study. It seems that the brain (more than the heart) is tuned on high intensity, and it is no surprise that variation helps to keep it fit an to prevent Alzheimer's disease and other forms of dementia.
