Pat, From this article http://human-nature.com/nibbs/03/crying.html: "The composition of tears is proteins (lysozyme, lipocalin and lactoferrin), enzymes, lipids, metabolites and electrolytes. The protein concentration differs between emotional tears and the tears produced by irritants. The complex composition of tears, though, differs throughout the daily cycle of human existence." Tears seem to be a lot like breastmilk.
