8. World's Oldest Virgin (105 years old)



World's oldest virgin has revealed the secret of her longevity on the eve of her 105th birthday — no sex. Clara Meadmore has never had sex in her life because she has always been 'too busy' for intimate relationships and it seemed like 'a lot of hassle'. Miss Meadmore, who remembers the Titanic sinking and the outbreak of the First World War, said she knew she would remain single from the age of 12, and abstained as a young woman in order to concentrate on earning a living. The former secretary says she has no regrets about remaining a virgin and had turned down several marriage proposals.

9. World's Oldest Prom Attendee (84 years old)



He arrived in style: a black limo, a sharp tuxedo, a beautiful date and an adoring crowd waiting for him. Eighty-four-year-old Kenneth Smith attended the Chester High School prom night fashionably late. Decades late. Smith was drafted into military service in 1943, before he could finish high school. He returned home after World War II but never got his high school diploma. A friend arranged for him to receive an honorary diploma from Chester High School, just outside Philadelphia, and finally go to the prom. He did — at the Springfield Country Club. Smith said this prom wasn't just for him. He said it was also for all the other soldiers who couldn't make it to their own.
