Lust & Death
Remember, you can’t have one without the other!
How does an amoeba reproduce? It eats. And eats. And eats some more. And when it’s had just enough to burst, it turns into TWO amoebas! Immortality through binge eating! And we have the nerve to call ourselves “higher organisms!”
No, we have sexual reproduction, which means two creatures have to get together to make one new creature. And then, to add insult to injury, the two creatures that got it on to make the one new one have to go and die, as to not strain the food supply for the youngsters and their offspring.
To have a thankless child! Away, away!
