Spurred by a near epidemic occurrence of brain-degenerating conditions as we age, people of all ages and backgrounds are stepping up their personal efforts to improve and maintain their brain health. According to a story in USA Today, sales of brain fitness software reached nearly $230 million in 2007. USA Today stated, "SharpBrains, (a market research firm) estimates the brain fitness software market will reach $2 billion in 2015 in the United States."

Prudent investment strategy might include a speculative foray into this popular and growing field. In light of this, you may wish to pay heed to blogger Steven Mallas, and read his take on Activision (NASDAQ: ATVI).

First on the list for brain maintenance is physical activity, which probably accounts for the outstanding sales of Nintendo's Wii Fit. from Nintendo Ltd. (OTC: NTDOY). Active lives promote healthy blood circulation, which helps to feed steady amounts of oxygen to the hungry brain. Good hard work, cardiovascular exercise and even regular sexual activity can all help to keep your heart pumping adequate levels of oxygen into your brain.

According to the AARP, we should seek simple, inexpensive, no-nonsense strategies which we can employ to help maintain our brain's functionality. This might give us inspiration to seek out some of the great brain exercising software now available. Additionally, you could improve your business performance at the same time by accessing management training from companies such as Learning Tree International Inc. (NASDAQ: LTRE), which provides information technology and management training.

Keeping your brain stimulated is essential to its health. It's my opinion that when learning stops, we're dead. I believe that we should continue to pursue learning opportunities as we age. According to blogger Steven Halpern, I'm not alone in this belief, and he cites as proof, New Oriental Education (NYSE: EDU). Steven gave us a good look at the company in a recent blog post.

Finally, just take good care of yourself. A healthy diet, a good attitude, effective stress management, and adequate sleep, all work in concert to help maintain brain fitness. Most importantly, I think that the key to an active, and therefore healthy brain, is to stay as engaged with life as possible. Don't give brain sluggishness a chance to creep in. Invest in mind shaking software, read with a hunger, and explore new ideas.
