Pretty much says it all right there. If it is always on your person, except in the shower or asleep in bed, it isn't an issue.
Some people can't imagine wearing pants with a belt on, wearing a wrist watch, wearing shoes, you name it, unless there is a "reason". Some just do it out of habit, never bother with needing a reason.
This isn't meant to sound snarky or "tactically elite", however you define it. Just habit.
