During testing for the advanced level swim qualification in the Marine Corps, you have to rescue a person who is basically trying to drown you. The testing instructor is acting like a drowning, panicked person. The test is hard to pass and wears you the hell out. Getting your head pushed under constantly sucks. I passed it (WSQ 1) but it was a challenge. Out of 8 of us, 3 of us made it. Other two were new Ch-46 crew chiefs. That tells you how long ago that was.

"...aspire to live quietly, and to mind your own affairs, and to work with your hands, as we instructed you, so that you may walk properly before outsiders and be dependent on no one." - Paul to the church in Thessalonica.
