...and people who study this stuff are not wrapped too tight..
I once saw a National Geographic documentary called: Mummifying Alan: Egypt’s Last Secret.
It was about a guy who donated his body to be mummified like a Pharaoh from ancient Egypt. I was especially interested when they explained what salts they used and where it came from. I thought he came out well preserved like a piece of leather. You may want to watch it.
