When I first stepped into the tiled bathroom stall 5 years ago, I was soon overwhelmed by the so-called "squat toilet". They have neither covers nor seats and are simply porcelain bowls in the floor. Some doctors have said that the squatting position is considered the most natural and efficient way to go to the bathroom. However, I have been using a sit-down toilet my entire life and haven't squatted since childhood, squatting may present somewhat of a physical challenge-to say the least! I can't read the newspaper or have a cup of coffee on the squatter. And also, I am 65 years old; it may seem tough on the knees and ankles.
