Luu Cong Huyen, a 58-year-old man from Yen Giao in Vietnam's Nam Dinh province, has been growing his nails for more than three and a half decades. He is very careful with his hands and avoids any activity that could cause an accident. He claims:Some people like raising birds, planting trees or collecting old vehicles... I just like having long nails; letting nails grow is harder than it seems. I have to be very careful in all of my movements to keep my nails in good shape.A complicated hobby because his nails - the longest is about 55 cm - are very fragile. He has to avoid shocks and especially moisture, which makes them brittle. What's more, he rarely takes baths and the few times he does, he has to ask his wife, Nguyen Thi Thuan for help, who also sometimes feeds him with a spoon. Luu puts his hands in plastic bags when he goes out in order to protect his nails from the rain. He has to be very careful in every activity, even to put on a t-shirt.Luu has, in the past, broken one of his nails, which devastated him. He said he would rather die than break a second one.
