Another reason why I need to excerise more...

After reading this CNN article, it's even more obvious why a little exercise is good for more than just your body. It's warm enough today here to drag out the bicycle, or at least take another walk, especially knowing:

Tests on mice showed they grew new brain cells in a brain region called the dentate gyrus, a part of the hippocampus that is known to be affected in the age-related memory decline that begins around age 30 for most humans.

The researchers used magnetic resonance imaging scans to help document the process in mice -- and then used MRIs to look at the brains of people before and after exercise.

They found the same patterns, which suggests that people also grow new brain cells when they exercise.

We all could use a few new brain cells, I killed off more than a few in my lifetime...
