There are sailors now born in the 90's!

That, to me, is gonna be a tough one. As a Div-O, I'm going to be younger than a lot of my junior enlisted. I guess how old I am shouldn't even ever come up, but still gotta get my own head around that.

I'm a Divo. I'm 24. Until recently, my shop was all older than me.
It will come up, and for me, it always comes up in relation to music. For instance, when listening to your iPod at work and someone mentions that they listened to X song at their prom, and didn't you like it in high school too? Except you were actually in elementary school at the time.
Just admit how old you are if anyone asks, and then move on. It's not an issue unless you make it one.
