Under The Weather.

Back in the glory days, when ships made of oak and pushed by winds ruled the seas, the unfortunate sailor who had to stand watch on the lee of the ship at the bow was subject to the wind and waves and spray as his home continued to push across the boundless sea.

Such a man was said to be "under the weather". Exposed to it all. Standing sentry - usually alone - up at the bow.

While I am not in that state right now, I certainly fall under the modern meaning of the phrase.
