I don't care what happens to my body after I'm dead. I don't care cause I can't.
I used to think cryogenic freezing though, just cause, why the hell not? Then I found out that it costs like 100 grand, so **** that.
Related pet peeve: People who aren't going to donate their organs after they die. You're not going to be using them anytime soon, why not give them to someone who can use them?
And I've heard the argument that it's because the organs don't always go to people who need them, sometimes they go to scientists. Well who the hell cares? If you don't donate they're just dust.
