Writing philosophy offers its own kind of immortality, much like the canine transmissible venereal tumor

That, the Tasmanian Devil face cancer, and one other are the only known transmissible cancer. Don't know what the third is.

oh man there’s a third??? I only knew about those two

tree burls are a thing too. they're somewhere in-between scar tissue and benign tumors. transmissible both through pathogens (viruses, fungus, and insects) and probably also through grafting/cloning (though that would require human intervention).

whaaaaaaaaaat
