hair and beards for practical reasons. Men in some regions bleached their hair a golden saffron color. Females also had long hair, with girls often wearing it loose or braided and married women often wearing it in a bun. The average height is estimated to have been for men and for women. The three classes were easily recognisable by their appearance. Men and women of the Jarls were well groomed with neat hairstyles and expressed their wealth and status by wearing expensive clothes (often silk) and well crafted jewellery like brooches, belt buckles, necklaces and arm rings. Almost all of the jewellery was crafted in specific designs unique to the Norse (see Viking art). Finger rings were seldom used and earrings were not used at all, as they were seen as a Slavic phenomenon. Most karls expressed similar tastes and hygiene, but in a more relaxed and inexpensive way. Archaeological finds from Scandinavia and Viking settlements in the British Isles support the idea of the well groomed and hygienic Viking. Burial with grave goods was a common practice in the Scandinavian world, through the Viking Age and well past the Christianization of the Norse peoples. Within these burial sites and homesteads, combs, often made from antler, are a common find. The manufacturing of such antler combs was common, as at the Viking settlement at Dublin hundreds of examples of combs from the tenth-century have survived, suggesting that grooming was a common practice. The manufacturing of such combs was also widespread throughout the Viking world, as examples of similar combs have been found at Viking settlements in Ireland, England, and Scotland. The combs share a common visual appearance as well, with the extant examples often decorated with linear, interlacing, and geometric motifs, or other forms of ornamentation depending on the comb's period and type, but stylistically similar to Viking Age art. All levels of Viking age society appear to have groomed their hair, as hair combs have been found in common graves as well as in aristocratic ones. Farming and cuisine The sagas tell about the diet and cuisine of the Vikings, but first hand evidence, like cesspits, kitchen middens and garbage dumps have proved to be of great value and importance. Undigested remains of plants from cesspits at Coppergate in York have provided much information in this respect. Overall, archaeo-botanical investigations have been undertaken increasingly in recent decades, as a
