Many people wear orthotics or various types of “arch supports” because they have either flat feet or pain in their arch. Flat feet are normal in a toddler; as they get older the tendons in the foot strengthen and tighten to form the medial longitudinal arch, often by the age of three. Some never fully develop this arch in the foot, often due to poor footwear. Many adults have what appears to be an arch when they are non-weight bearing but the arch flattens or fatigues when they stand due to muscle, tendon, and ligament weakness in the lower leg and foot.
In southwestern Europe (Portugal, Spain, and France) and in the northern half in Finland especially, larger lampreys are still a highly prized delicacy . Sea lamprey is the most sought-after species in Portugal and one of only two that can legally bear the commercial name "lamprey" ( lampreia ): the other one being Lampetra fluviatilis , the European river lamprey , both according to Portaria (Government regulation no. 587/2006, from 22 June). Overfishing has reduced their number in those parts. Lampreys are also consumed in Sweden, Finland, Russia, New Zealand, the Baltic countries , Japan, and South Korea.
