Social panic is a great excuse, a subterfuge used by cowards to avoid disclosing sensitive information. Data that, if known, rather than generating collective fear, would help to save lives.

1990 was a tremendously turbulent year for Madrid and, more specifically, for one of its neighborhoods: Cerro Belmonte.

Because of this peculiarity, they look like creatures out of some disturbed mind, but they are very real, both they and their bloody “weepings”. They do not “weep” blood because they have seen something horrifying, but because it is an extremely curious defense mechanism.

Snakes have often been associated with evil, either for cultural reasons or, directly, because of our survival instinct. We fear and respect them and the venom they use to hunt and defend themselves.
