Lou Ferrigno became a household name as the "The Incredible Hulk," starring in the classic TV show in the 1970s and 1980s. But the two-time Mr. Universe and fitness icon has always had one weakness - his hearing. After ear infections as a toddler left him with major hearing loss, Ferrigno spent years wearing hearing aids. At 69, he decided to undergo cochlear implant surgery to improve the clarity and definition of his hearing. Just like the Hulk, the results were incredible.
