The 2007 Guinness Book of World Records, which comes out Thursday, features two people who have broke the mold when it comes to personal grooming - one with fingernails that are 24 feet and 7 inches long, and another whose hair sticks up 24 inches above her head.

Sixty-five-year-old Lee Redmond, from Utah, says keeping up her fingernails takes a lot of care.

She tells Reuters, "I clean them with a toothbrush when they get dirty and always keep them manicured." She applies olive oil and nail hardener to them every day.

However, Redmond plans to get rid of her nails soon, so she can make better use of her hands.

"I am going to have to take them off in November as I am looking after my husband who is suffering from Alzheimer's," she says.

Aaron Studham, 17, says he grew out his 2-foot-high mohican on a dare.

He says, "It took me five to six years to grow. I don't wear it up all the time but when I do, it takes about 45 minutes to an hour to put it up. I use hairspray and then blow-dry it."
