If i wanted to eat something through my ANUS and have it be digested then exerted back out, could i do it without dying? Say if i put a muffin up my ANUS i could use my ANUS muscles to push it up. but i could also use compressed air to push it all the way up through the digestive system. Someone try this! Someone who is willing to risk their life for teh greater good! What will this be used for? Think of the efficiency!
