TOHCan, you seem like a smart guy. I have to admit you were the only guy who recognized that I misspelled "ignorance." However, I am pretty sure you meant to imply, so that we'd all infer ... not the other way around. Check out a Dennis Quaid movie called "DOA."
And here I was thinking you meant the lipid based oils that do not dissolve in water, such as, perhaps, Vasoline ... (though I admit I think that one is in fact petroleum based and not lipid based. But, what do I know? I'm not a biochemist.)
