What are the advantages of having toilets?

Without toilets, humans would need to squat to have a bowel movement. Women would need to squat to urinate, and would risk getting urine on the inner thighs, legs, and feet. Besides the comfort of sitting, toilets also allow for privacy (versus going behind a bush). Further, toilets take waste away in a simple flushing mechanism, which helps prevent illness and disease from being transferred to other people.
