LOL hanadr, I agree, Mercola is a nut, there are lots of nuts out there though...but this breathing exercise is really good, breathing exercises are also part of yoga, etc
I am doing voluntary work with nervously ill people, anything from phobias to panic attacks and depression, as part of this I teach Relaxation and that includes breathing exercises, this is important for everyone, so in this instance Mercola is definitely not a nut, even if he chooses to do the exercise while giving thanks for his food or during eating, probably his way of avoiding indigestion?
