Short Showers
Long luxurious showers are basically unheard of when you are in the military because there’s no time for them. Showers are brief because they are nothing more than a necessity. Soldiers usually still have this habit even when they are back to civilian life.
Sunglasses
If you’ve been or still are in the military, chances are you feel more comfortable sporting sunglasses. The sun shining or not is not really an issue. Your will be wearing your sunnies regardless.
