Hah! Meditation good for you!

Take that, all you Type-A go-getters.

Meditation alters brain patterns in ways that are likely permanent, scientists have known. But a new study shows key parts of the brain actually get thicker through the practice.

Brain imaging of regular working folks who meditate regularly revealed increased thickness in cortical regions related to sensory, auditory and visual perception, as well as internal perception -- the automatic monitoring of heart rate or breathing, for example.

The study also indicates that regular meditation may slow age-related thinning of the frontal cortex.

So when your frontal cortex is all thin and old, remember this even as you forget your street address - that I told you so.
