If you're ever adrift...

Right now there's a sailor adrift at the edge of the world-- Cape Horn. I was reading about it with my mom tonight, discussing lifeboats and rescue attempts in ocean conditions, and we had this conversation:

"You do know the sailor's rule of thumb, right?"

"Which rule of thumb? I've got two thumbs." (I've also gotten quite a few sailor's rules of thumb growing up)

"Never step down into a lifeboat. Step up into a lifeboat."

EDIT: The guy's been rescued this morning.
