I taste so salty that my horse used to use me as a human salt lick. I guess by Jen's definition that makes me very sexy? <img src="i/expressions/face-icon-small-wink.gif" border="0">
I can't vouch for the accuracy of this statement, but when my doctor was explaining mutations one of the things I remember her telling me was that certain mutations allow for some (limited) salt transfer and others (such as the DF508 mutation) allow for zero transfer. If there is zero transfer, it would stand to reason that your sweat, and thus your skin, would taste saltier, as less would be absorbed into your body. This is one of the reasons DDF508 is considered a "severe" mutation, while some others are considered more mild (although obviously every individual is different). Also, of course, some people have one DF508 and then another mutation that allows for limited transfer.
I have one DF508 mutation and one CFTR gene deletion, which of course also allows for zero transfer, so that would make sense with why my skin is as salty as the DDF508 people.
