delinquent noun [C]. âº a âperson, usually âyoung, who âbehaves in a way that is âillegal or not âacceptable to most âpeople: âjuvenile delinquents.
Sahelanthropus may have walked on two legs. The oldest evidence for walking on two legs comes from one of the earliest humans known, Sahelanthropus. Walking upright may have helped this species survive in the diverse habitats near where it livedâincluding forests and grasslands.
Walking can help increase blood flow to the legs and promote the growth of tiny blood vessels that help supply the leg with blood and oxygen. It had been thought that aspirin wouldn't work because its anti-inflammatory properties could block the development of these tiny blood vessels that grow to get blood around the blockage.
