Why is the "dead weight" of someone (e.g. an unconscious person or dead body) heavier than "live weight" (e.g. a conscious person)?

When someone is live weight they often put their arms around you. This spreads the weight more evenly making it easier to lift them.

Their weight remains the same. However, with a dead body, rigormortis sets in. The body goes a lot stiffer. Not only can the person who is being lifted not help you by wrapping their arms around you, but you owuld find it a lot more difficult to wrape their arms aroung you yourself. Then the forces of "moments" comes into play. You will need to carry the body near its central weight or you will keep tipping. The more a body is wrapped around you, the less of a problem this would be.
