Rick Rosner shares his first experience with a hearing aid, describing a thirty percent hearing loss at certain frequencies and the improvements in clarity it brings, from sharper environmental sounds to better communication at home. He reflects on his grandfather’s decline due to sensory deprivation, including hearing loss, poor vision, and ill-fitting dentures. Rosner emphasizes the importance of maintaining sensory input to prevent brain atrophy, a concern reinforced by his wife’s observations of her mother’s hearing loss. The conversation shifts to speculative futurism, imagining posthumanist “tech bros” enhancing and adding senses for heightened perception, merging natural evolution with advanced technology.
