Ötzi the Iceman suffered head injury

Ötzi the Iceman, Europe's oldest mummy, likely suffered a head injury before he died roughly 5,300 years ago, according to a new protein analysis of his brain tissue.

Ever since a pair of hikers stumbled upon his astonishingly well-preserved frozen body in the Alps in 1991, Ötzi has become one of the most-studied ancient human specimens. His face, last meal, clothing and genome have been reconstructed — all contributing to a picture of Ötzi as a 45-year-old, hide-wearing, tattooed agriculturalist who was a native of Central Europe and suffered from heart disease, joint pain, tooth decay and probably Lyme disease before he died.
