Benito Hernandez stands outside his home near San Jose de Las Piedras in Mexico's northern state of Coahuila January 16, 2013. For over 30 years, Hernandez, his wife Santa Martha de la Cruz Villarreal and their family have lived in an odd sun-dried brick home with a huge 40 meter (131 feet) diameter rock used as a roof.
