Not a brain surgeon here...some of the comments appear to just assume that whatever this means it must be good. Is it? Or are long term meditators doing irreparable brain damage to themselves? My gut feeling is that meditation will strengthen portions of the brain that control impulses and emotions, but I don't know enough about the brain anatomy referenced here to understand what's going on.
You'll see this on HN every time meditation comes up. Apparently a fair proportion of posters here are convinced that meditation is self-evidently and infallibly beneficial.
Rather than driving by with some shade, you could see for yourself. It is self-evidently beneficial but that requires putting the "self" in the self-evidently. This casual scorn does nothing good for anyone least of all you.
