One of the craziest guys I knew in high school, Andrew Heino, went to the Naval Academy and the last time I saw him at a party during our college years, he said that getting through that summer was one of the hardest things he'd ever done.  He also said his whole first year was no picnic.  I haven't seen him since then, but every once in a while I'll catch word of him.  In February, 2007 he was interviewed on CNN's Accent Health show about some of his men doing yoga and at that time he was a Lt. Colonel in the Marines.  That comes as absolutely no surprise to me.  

Heino was the guy who got me through an open water test for our SCUBA class in freezing water in a quarry in West Virginia.  On that dive the visibility was about one foot and the water was literally freezing and when we got down to the dive platform (I think it was at about 50 feet) the guy next to me went into shock and the dive instructor had to do an emergency ascent with him.  There was another instructor around but we couldn't see him and I was ready to head up, but Andrew grabbed me and signalled to sit tight.  We did and eventually the instructor came back and we finished our test.  That's the kind of guy Heino was.  Also, he could recite every line of Apocalypse Now verbatim from memory, and I guess that says something too. Heck, the fact that he talked me into taking a SCUBA class says a whole lot about him.
