It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the blessed head of the Prophet (peace and blessings of Allah be upon him) was large. His (peace be upon him) eyes were very prominent. When he walked, he would lean slightly forward, as if he were descending from a slope. When he turned his attention to someone, he would turn to them completely.
Benefits and Issues: Not giving someone your full attention, speaking with one person while your focus is elsewhere, is contrary to high moral character. Walking briskly and speaking with complete attention is not contrary to modesty (haya), nor is it considered harshness.
