Immortal McHorror burger is 12 years old, looks just like new

En Best of Mother Earth, via BoingBoing. La cita es del articulo en BoingBoing:

McDonald’s should add “immortality” to its list of Unique Selling Propositions for its burgers (unless Karen has an ornate oil painting of the burger in her living room in which it slowly ages, grows mouldy, and decomposes).

Cuando vi la imagen pense que la hamburguesa de la derecha era la inmortal. Me pregunto como las hamburguesas de Burger King se conservan.
