Corpses may have earned the moniker, stiffs, but they dont stay stiff forever.
Hair and Nails Continue to Grow After Death.
Its baffling how many people believe this happens.

Dexter
Nails and hair are made from a material called keratin, which consists of multiple layers of dead cells.
Nail and hair growth triggers when new living cells form and push the dead ones out into the world.
When a person dies, this activity ceases, which means no more growth occurs.
Seems obvious, right?
They are either messing with you, or a coworker was messing with them and they didnt realize it!
If they did, Id probably quit my job!
The most they might do is twitch a little immediately after death.
This phenomenon related to rigor mortis is known as a cadaveric spasm.
Not going to happen.
Corpses Are a Bunch of Stiffs.
Corpses may have earned the moniker, stiffs, but they dont stay stiff forever.
In fact, they may not even get stiff to begin with, depending on the cause of death.
Initially the muscles of the body relax following death.
Typically rigor mortis starts to set in around 612 hours later.
These times vary based on the cause of death and the bodys immediate environment.
Oftentimes, additional testing is required.
This can take months due to backlogs at state laboratories.
In some cases, the cause of death may never be fully known.
This means you wont be able to read the autopsy report in its entirety right away.
Death Investigation is Done by CSI.
In the United States, Crime Scene Investigation (CSI) is completely different from forensic death investigation.
CSI deals with evidence such as hair, fibers, shoe prints, etc.
They collect this evidence and send it to be processed at a crime lab.
The Zombie Apocalypse is Coming.Well, it could be.
No one really knows for sure.

A mortician can also be elected as a coroner.
Its also good to know that not every state has coroners.
Youre Going to Be Buried in a Coffin.
If you live in the United States, youre more than likely going to be buried in a casket.
Morticians are very particular about using this correct terminology and even study the parts of the casket in school.
So heres the deal.
European countries often use coffins, which can range from simple to lavishly decorated.
The Eyes Stay Closed After Death.
Its rare that decedents eyelids will stay closed after death.
Its also not unusual for someone to die with their eyes open.
Its actually quite natural and occurs due to muscle relaxation around the eyes.
Another fact: the same thing happens with the mouth due to jaw muscle relaxation.
