I think what's holding me back from being a vegan is the contradiction.
On the one hand I'm eating vegan, which would make me want to kill myself, but I'm eating vegan because it's healthier, which means that I want to live a longer life.
Unless I want to be in peak shape when I die. A healthier corpse to lug around has its benefits for the living. Not as heavy. Less makeup needed for the viewing. Look good in a suit.
Is this too morbid?
