The International Association of Plumbing and Mechanical Officials (IAPMO) requires public toilet seats to be U-shaped for hygiene and other reasons: Hygiene: U-shaped seats keep the user''s most sensitive areas away from the toilet, which could have unwanted droplets on it. They also eliminate areas that could be contaminated with urine and prevent genital contact with the seat. Wiping: The U-shape gives women more room to wipe without having to stand up or touch the seat directly. Cleaning: The open front of the seat makes it easier for users to clean up. Cost: U-shaped seats are cheaper to manufacture and more affordable for businesses to purchase multiple seats. Safety: The open front of the seat keeps users safe from debris.
既然这么好为什么家里的不采用
家里尿歪了有老婆/老妈骂，所以瞄的比较准。外面随便尿。
