Shridhar Chillal is an Indian man known for holding the Guinness World Record for the longest fingernails on a single hand. His nails measured a total length of 29 feet 10.1 inches (9.1 meters) when they were finally cut in 2018, after growing them for over 66 years. Chillal began growing his nails in 1952 after an incident where a teacher scolded him for accidentally breaking a nail. He faced various challenges due to the length of his nails, including difficulties in daily activities. After cutting them, he donated his nails to the Ripley's Believe It or Not! museum.
