I've seen these too! One of them had an explanation, sort of, if I'm remembering correctly. I think it has something to do with holistic health...Meridians are like the energy channels that are often referenced in holistic healing and exercise, specifically acupuncture, tai chi, and yoga. I found this: http://mn-acu.blogspot.com/2010/12/proven-method-to-cure-cold-make.html 'In Traditional Chinese Medicine (TCM), sneezing is a natural reaction of our body trying to repel the wind cold with the heat generated during the sneezing process. Therefore, why not sneeze more? This is the reason behind our method today – Make yourself sneeze.'
