Here’s a good article on the recent findings that meditation increases the thickness of your brain. The study found a correlation between the length of time a participant had meditated and the thickness of their brain in the area devoted to attention and memory. Over time brains tend to get thinner there, so in this case, meditation was found to actually reverse the usual effects of aging.

The ‘control group’ just sat instead of actively meditating. I’ll remind myself of this when I’m on my cushion and catch myself reliving the previous night’s episode of Lost.
