Diana Armstrong of Minneapolis recently earned the Guinness World Record title for the longest fingernails with a combined length of 42 feet and 10.4 inches. Armstrong says she's been growing out her nails for over 25 years -- but she didn't set out to break any records. Her reason for doing it was actually born out of heartbreak. She lost her daughter at the age of 16 to an asthma attack. The night before she died, her daughter gave her a manicure, and she just couldn't bear the thought of cutting them after that.
