wow that is one big pool! I would love to have a pool like that! I wonder how many people it can hold, or how long it took to make?

The world's longest documented hair belongs to Xie Qiuping (China) at 5.627 m (18 ft 5.54 in) when measured on May 8, 2004. She has been growing her hair since 1973 from the age of 13.

That is really long hair, if i tried to grow it that long I would get frustrated and cut it off. That is a very long time to grow hair. what a great Guinness world record!

The tallest man in medical history for whom there is irrefutable evidence is Robert Pershing Wadlow. He was born at Alton, Illinois, USA, on February 22, 1918, and when he was last measured on June 27, 1940, was found to be 2.72 m (8 ft 11.1 in) tall.

Wow that is really tall!! i cant believe its possible for someone to grow that much. it must have been hard getting around, barely fitting in houses.

Wow i would never pay that much for a guitar, even though its really nice. that's like more than a car, that person must have really wanted it!
