What does a dead body look like after 2 weeks?
3-5 days postmortem: as organs continue to decompose, bodily fluids leak from orifices; the skin turns a greenish color. 8-10 days postmortem: the body turns from green to red as blood decomposes and gases accumulate. 2+ weeks postmortem: teeth and nails fall out.

Do bodybuilders sink in water?
