Perch on other individuals of the same species without there being a reproductive, or at least sexual, interest, it is a matter only of the human species. And within the human species, it does so only the subspecies of the ‘castellers’. I will not be the one to criticize those who dedicate themselves to such a peculiar pastime, which must have everything in this life, not even to those who enjoy looking at it, which is even rarer, Not even the animals do that. I haven’t seen the other lions watching while one of them climbs on top of the lioness in any of La 2’s documentaries. What I don’t quite understand is for what reason in each citizen celebration the ‘castellers’ must come to climb on top of each other.
