Bending

N. Decompression sickness, caused when a diver moves from a high-pressure environment to one of low pressure too rapidly, causing bubbles to form in their bloodstream as gases in pressurized, liquid form quickly revert to their natural state. Symptoms include: blotchy rashes, coughing spasms, dizziness, unconsciousness, and a bizarre inability to bend joints (hence, the phrase the bends).
