Good news for us long-time meditators: a study shows that meditation is linked to psychological well-being, which in turn is related to higher telomerase -- an enzyme that makes cells healthy.
The study participants had one-third more teomerase in their white blood cells than controls. However, this was only after they spent three months in an intensive meditation workshop that entailed six hours of personal meditation a day plus a couple of group sessions.
I have a feeling that this would drive me nuts, rather than healthy, but I could be wrong. Regardless, I'm hoping that my current 20-30 minutes of daily meditation along with regular enervating boosts of maxi-scooter riding and red wine drinking will have the same effect.
