Prevent dementia in 2 hours a week

Right now, the world's leading drug companies are sinking billions into dementia drugs -- but they may as well be throwing their money into a black hole.

For all the billions they've wasted, they have absolutely nothing to show for it. There are no drugs that can prevent the disease, nothing to cure it and nothing that can permanently slow its effect on brain cells.

But that doesn't mean there's nothing you can do about dementia.

One of the most common markers of dementia is a shrinking brain. While all our brains shrink a little over the years, dementia is almost always accompanied by a faster rate of shrinkage.

Now, new research uncovers an easy way to not only slow that shrink, but to stop it completely and even reverse it -- to grow new brain cells and actually add gray matter at a time when everyone around you is losing it.

And all you have to do is go for a brisk walk.

That may not be the billion-dollar discovery Big Pharma is looking for, but the benefits are priceless for you -- because a brisk 40-minute walk three times a week can cause your brain cells to grow by 2 percent over the course of a year, according to the study of 120 men and women between the ages of 55 and 80.

Meanwhile, a control group asked to do stretching instead of walks saw their brains shrink by an average of 1.5 percent, or just what you'd expect to see in that age group.

In plain talk, that means the brains of the stretchers continued to age, while the brain cells of the walkers actually got younger. In fact, that 2 percent boost in brain volume among the walkers is equal to wiping out the effects of two years of aging.

It's as if we've found a way to turn back time, at least in the brain.

Pretty good, right?

But the benefits don't end there. A steady walking habit can fight disability, prevent diabetes, protect the heart and even lift your mood -- and that's still not all a little regular movement can do for you.
