Rigor mortis is the stiffening of joints with particular attention in the hip area. This is most common in people who shoot the DTL discipline. Overtime patients with Rigor mortis also lose almost all movement of the latitude and longitude axis. Sufferers are also known to slur their words over time with particular attention paid to the word PULL.
