 Jay, again, it goes to that concept that calcium constricts, magnesium relaxes. We can't because our diet is usually a little too rich with calcium-related type foods, and we don't get that magnesium. If we don't have that ability for our blood vessels to relax, for our heart to relax, how can we experience that healthy heart rhythm? You know, magnesium was in the diet a century ago, but it's not here now.
