He lost his sense of smell after being hit by a car — and it's slowly stealing his joy of living

Dear Doctor Roach: My 82-year-old husband is unable to smell or taste. This has been the case since 2024, when he was hit by a car while out for a walk. He sustained a compression fracture to his spine. While he wasn’t knocked out, he did get thrown backward and sustained some trauma to his head. Since then, he’s had no sense of smell or taste.
