reference my previous post, the basic point is efficiency. You assume
access to a voluminous supply of fresh water because the tears are not
concentrated (isotonic). Is this likely to be a major method for salt
balance? Why argue minutia, it doesn't effect the basic premise that
tears are going to affect the salt balance of the organism. They are not.
