You might be struck by movement everywhere as cars and people go about their business, by the sound of a street musician\u2019s melody or a horn honking in the distance, by the smell of exhaust fumes or of food being sold by a nearby vendor, and by the sensation of hard pavement under your feet.<\/span><\/p>\r\n<p class=\"os-caption-container\"><span style=\"text-align: initial;font-size: 1em\">We rely on our sensory systems to provide important information about our surroundings.
