Car mechanics tell you the truth. You don't give a rat's ass if someone notices your new haircut. The world is your urinal. Hot wax never comes near your pubic area. You never have to drive to another gas station because this one's just too icky.
Wrinkles add character.
You don't have to leave the room to make emergency crotch adjustments. If you retain water, it's in a canteen. People never glance at your chest when you're talking to them. The occasional well-rendered belch is practically expected. New shoes don't cut, blister, or mangle your feet.
