Nonsense. Find a single peer reviewed study published in a respected journal that supports your statement.

Want to find the healthiest people on the planet? Better look in Japan and Sweden. When you find them engaged in "self or audio" meditation let me know.

So much BS ... good thing we have the internet to spew it about.
