[Wiki] World is mad

I was reading some stories today (as every day) and on some picture I saw Gerardo Medina as infant. From the title one can read that till the age of 10 he thought that girl (Lina Medina) next to him on this picture is his sister. But she was his mother, she gave him a birth when she was 5. Below is the picture I’ve found and you can learn more from article on Wikipedia.

In such occasions I really wonder if world would ever stop to surprise me. And disgust me as well.

UPDATE:
I’ve found a book which can put more light on Lina’s case, however there is no digital edition:(
