The real path to immortality is to convert your body into plastic, so you can slowly disintegrate and be dispersed into the great Circle of Microplastics
I saw that Body's exhibit when it came to the local science museum. That's really cool how the bodies were preserved and the man-hours that go into just one body are wild!
If it makes it to the transfer station in my town, it will end up in the waste-to-energy plant. It's not optimal but the system does treat the air it releases and the slag isn't as toxic as coal dust. Just one of those expensive systems that's a better use of land than to use it as a dump.
Nah, not if I throw it into the ocean it won't. It's remains will flush through my media consumption damaged, but otherwise semi-functioning brain long after the waves grinded it into microplastics.
