Car mechanics tell you the truth. The world is your urinal. You never have to drive to another gas station restroom because this one is just too icky. You don't have to stop and think of which way to turn a nut on a bolt. Same work, more pay. Wrinkles add character. Wedding dress: $5000.00. Tux rental: $100.00. People never stare at your chest when you're talking to them. The occasional well-rendered belch is not only appreciated by your friends, but practically expected. New shoes don't cut, blister, or mangle your feet. One mood all the time. Phone conversations are over in 30 seconds flat. You know stuff about tanks.
Read the whole thing. It certainly convinced me.
