It was at first believed that the Iceman was free of diseases, but in 2007 researchers discovered that his body had been infested with whipworm and that he had suffered from arthritis; neither of these conditions contributed to his death. He also at one time had broken his nose and several ribs. His few remaining scalp hairs provide the earliest archaeological evidence of haircutting, and short blue lines on his skin (lower spine, left leg, and right ankle) have been variously interpreted as the earliest known tattoos (tattoo) or as scars remaining from a Neolithic therapeutic procedure. The various clothes and accoutrements found with him are truly remarkable, since they formed the gear of a Neolithic traveler. The Iceman's basic piece of clothing was an unlined fur robe stitched together from pieces of ibex, chamois, and deer skin. A woven grass cape and a furry cap provided additional protection from the cold, and he wore shoes made of leather and stuffed with grass. The Iceman was equipped with a small copper-bladed ax and a flint dagger, both with wooden handles; 14 arrows made of viburnum and dogwood, two of which had flint points and feathers; a fur arrow quiver and a bow made of yew; a grass net that may have served as a sack; a leather pouch; and a U-shaped wooden frame that apparently served as a backpack to carry this gear. His scant food supply consisted of a sloeberry, mushrooms, and a few gnawed ibex bones.
