Why do we call it dead bodies? Nobody says alive bodies! like you walk into your workplace, "OMFG ITS FULL OF BODIES! Alive ones tho." You wouldn't give birth and say, "Come on husband, help me with the bodies." If its a surprise party, you wouldn't say, "QUICK, HIDE THE BODIES!" And the person who the party was for wouldn't say "OH MY GOD WHY ARE THEY DEAD!"
