This young man was jogging on a Georgia recreational park trail, on a sunny day. He was wearing a sleeveless, gray tank-top shirt, and black shorts, both of which protected this runner from the sun’s harmful rays, and kept him cool throughout his run. His running shoes were specially designed for this kind of activity, affording the needed support, and comfort to his feet. He had applied sunscreen to his sun-exposed skin, protecting him during his long-term ultraviolet light exposure. Though he carried no water, he had brought bottled water, which he’d ingest when he reached his vehicle.
