The Netflix show "Altered Carbon" adopted this concept from this book perhaps. In the show the bodies were disposable, consciousness/memories all lived in a jewel like object fit into spine in the neck. Physical damage to bodies done in violence was referred as 'organic damage'. Rich people could live forever using grown bodies, while the jewels of poor were moved to an archive.
