I only got back into reading last year when I joined a book club and the first book I read as part of that club was Smoke Gets in Your Eyes: And Other Lessons from the Crematory by Caitlin Doughty, which completely opened my eyes to the death industry (at least in the United States)
talking about corpse stuff
The worst part was when families would want to see the body before it gets cremated, so they do a lot of weird shit to the corpse to make it look presentable and human. It's called embalming and the part where they "set the features" or make the face look normal really creeps me out. I really hope that when I die, my family cremates my body immediately instead of getting to look at my decomposing body one last time...
