Rachel, you probably know what I am about to say. "Why didn't I think of that?" I know about chi and the centers and all that stuff. Sorry, honey...........it makes perfect sense, but I like your piercing too.
It's a interesting concept, but not backed by science at all.
Not everything has to be proved by science to be a fact. But, please, let us NOT get another thread on alternative medicine going here.
When I first took yoga, (not the exercise classes, but the meditation kind) he talked to us about chi and meridians and how the main one is right at the navel.
The lower dan tien (chi center) is usually accepted to be a place a couple of inches below the navel and inward toward the spine.That may be true for men, whose navels are above their waists. Women's navels are just below the waist.
