UK's Garry Turner is able to stretch the skin of his stomach to a length of 15.8 centimeters (6.25 inches) due to a rare condition called Ehlers-Danlos Syndrome, a disorder of the connective tissues affecting the skin, ligaments and internal organs of only one in 10,000 people. The collagen that strengthens the skin and determines its elasticity becomes defective, resulting in, among other things, a loosening of the skin and hypermobility of the joints. In more serious cases, it can cause the fatal collapse or rupturing of blood vessels.
The skin on Mr. Turner's body is truly elastic. "If [you] … look at your own skin cells under a microscope, they'd be nice and round and lock in many places. … But my skin cells tend to be more jagged, and don't fit together quite so well," he said. "The best way to describe it is I'm built rather like a badly woven basket, if you can imagine that, which will pull apart."
