RIO DE JANEIRO (AP) -- Two brothers in Rio are living over the edge — literally: sleeping, working and eating on the side of a building 33 feet (10 meters) up in the air.

Twenty-seven-year-old Tiago Primo and his 20-year-old brother Gabriel spend 12 hours a day in the bed, hammock, chair and dining table they've attached to a bright red-and-yellow wall as part of an art exhibit in Rio's old center.
The brothers are equipped with mountain climbing gear, and if nature calls, can scramble over to the verandah of a neighboring art gallery, where an indoor bathroom awaits.
The brothers have been hanging out wall-side since the end of May. They plan to continue the display until Aug. 20.
