Pooping

Without pooping you will die. Respect.

From Wikipedia’s entry on Pooping:

Defecation or feceation is the act or process by which organisms eliminate solid or semisolid waste material from the digestive tract. Humans remove waste anywhere from several times daily to a few times weekly; sloths can go for a week or more without eliminating. Waves of muscular contraction known as peristalsis in the walls of the colon move fecal matter through the digestive tract towards the rectum. Undigested food may also be expelled this way; this process is called egestion.
