By 50 years in, your tissues will have liquefied and disappeared, leaving behind mummified skin and tendons.

What does a body look like after being dead for 2 weeks?
24-72 hours postmortem: internal organs begin to decompose due to cell death; the body begins to emit pungent odors; rigor mortis subsides. 3-5 days postmortem: as organs continue to decompose, bodily fluids leak from orifices; the skin turns a greenish color. … 2+ weeks postmortem: teeth and nails fall out.
How do you calculate time of death?
