About.com Chemistry notes that the time it takes for the onset of rigor mortis to occur depends on the environmental conditions at the time of death, as this affects the temperature of the body. About.com explains that colder temperatures speed up the rigor mortis process. The face is usually the first to set, followed by the body.
Rigor mortis typically lasts up to 72 hours, according to About.com. Afterwards, the joints unlock, and the muscles once again start to relax as a result of the body decaying.Learn more about Human Anatomy

According to the Encyclopedia of Death and Dying, two to eight hours after death, the body stops producing adenosine triphosphate and muscles begin to stiffen. This occurs in part because oxygen no longer circulates. Other post-mortem biochemical changes also cause abnormal contraction of the muscles because the body is unable to remove the by-product lactose from the muscles to prevent them from stiffening.Full Answer >
On average it takes about 30 minutes for blood alcohol level to peak after consumption of one drink on an empty stomach, explains the National Institute on Alcohol Abuse and Alcoholism, a council of the National Institutes of Health. Blood alcohol levels approach zero about 2 hours after consumption of that drink. An average 150-pound individual eliminates about 0.5 ounces of ethanol from the body per hour.Full Answer >
