As we age, the neurons in our brains lose the tree-branch-like connections between them. Researchers say that exercise is the best thing for your brain's health. But if you're not keen on that, there are a few things that you can do to keep your mind sharp.

Quit smoking. The brain of non-smokers generally performs better than a smoker's. This may be caused by the fact that smoking causes diseases that contribute to poorer brain function such as stroke and hypertension. Stop now; it is never too late to start reducing your risk to memory loss.

Drink moderately. If you're a heavy drinker, chances are that excessive consumption of alcohol can lead you to a sudden and irreversible memory loss. A drink a day, however, may reduce the risk of dementia as suggested by a research.

Mental exercise. Mental activities keep your brain agile and strong. Acquire new challenging skills such as switching to a new career or learning a new instrument or language. An active mind will stimulate brain growth by producing new connectors between your brain cells.

Heads up. When you're exercising, do not forget to protect your head. Someone who engages in swimming will have a lower risk of memory loss from someone who takes up mountain biking. Take precautions so that you won't have to deal with head traumas by wearing a helmet or other protective headgear.

Stress management. Whenever you can, keep your stress level at minimum. Recurring bouts of stress can make you feel anxious and depressed, which will prevent your brain to process memories effectively. Take a break and try to relax yourself by meditating. If you can find a long term solution for your stress management, that would be much better.
