Man grows nails for 15 years

Li Jianping, 43, of Shishi City, Fujian province, says the nails on his left hand are one metre long in total. He told the Straits City News he was very proud of them but admitted they could be an inconvenience at times. "I never go to crowded places. And during sleep, I have to keep my left wrist under my head to prevent the hand from moving," says Li, who owns a grocery store. The current length took 15 years to achieve, but he first started to grow them 23 years ago.
Nails grown for 15 years [via] would definitely put a damper on trying to pick food out of your teeth. That and picking your nose, ears, and scratching.
