It involves slowing down during meals, listening to your body's fullness cues, and appreciating food as fuel rather than indulging to the point of discomfort.
The washlet can replace toilet paper completely, but many users opt to use both wash and paper in combination—although use of paper may be omitted for cleaning of the vulva. Some wipe before washing, some wash before wiping, some wash only, and some wipe only—each according to their preference.
There isn't one single #1 hardest school, as rankings fluctuate, but Harvard University, Stanford University, MIT, and the California Institute of Technology (Caltech) consistently appear at the very top of lists for lowest acceptance rates (often below 4-5%), requiring exceptional academic performance and unique qualifications from applicants.
