nauseated/nauseous

Have you ever felt nauseous? That's interesting. Technically speaking, that's not even possible.

The difference between these two is a matter of semantics, really. If you're not feeling well, you're nauseated. The thing causing the sickness is nauseous. That could be a horrible smell or your brother. In some cases, those two could be interchangeable. Sorry.

I was nauseated by the nauseous smell emanating from the manure factory. I know they don't manufacture manure. It's just an example.

Now, if you'll excuse me, I have to think of another non-nauseous post for tomorrow that hopefully won't leave you nauseated.
