It's funny that people always answer like this "I'm already so perfect at wiping i can't imagine it getting better."
In a family of 4 the toilet paper usage in my house dropped by 90%. A purchase of toilet paper now lasted nearly 10x the length, a direct cost savings and reduction in waste into the sewer system.
Just cause you have this incredible mastery of wiping doesn't mean the world does. I'm proud of you and how clean you wipe though, congrats. I just wish you could imagine a world where you didn't get your pants wet ever time you use a bidet.
