Pierre is a 54-year-old chimpanzee with a whole new outlook on life. Fifty-four-year-old Pierre was completely blind before undergoing a cataract surgery that restored his sight. With this surgery comes a greater ability to move around his surroundings, participate in fun activities, climb more confidently, and control his dynamics with other chimps (Pan troglodytes). Oh forgot to mention, Pierre is a chimpanzee. He’s a resident at Chimp Haven, a chimpanzee sanctuary in Louisiana (and the largest in the world) where most of the chimps have retired from biomedical research.
