Acne and Assault Rifles

So, I made it to Afghanistan. I have been here a little over a month, but I have been pretty busy learning my new job so I have not had much of a chance to write. After being away from the military for some time, two thoughts have occurred to me since I have become reacquainted with my old profession:

1) I look at the soldiers that are around me, and I think, "man, I have gotten old!" and

2) should I be concerned when I see a young man with an m-16 slung across his back, putting on acne medication?

eh, it is probably just the fact that somewhere along the way I turned into an old fart....
