It's funny, after giving it some thought, what does everyone want to know/ask about? What makes guys quit. On the bus ride from the airport to the NAB Coronado, everyone was asking about what makes guys quit in the pool. Buddy tows, under waters, brick treads... In hindsight, fuck that. Ask about the guys that make it through. They're the only ones that matter. A million different things can make a guy quit, but the ones who succeed probably have many things in common.
HM was on my list, but it totally depends on manning levels at the time. Make it through your pipeline and it won't be a concern.
