Two paramedics were dispatched to check on a 92-year-old man who had become disoriented. They decided to take him to the hospital for evaluation. En route, with siren going, they questioned the man to determine his level of awareness. Leaning close, one asked, "Sir, do you know what we're doing right now?" The old man slowly looked up at him, then gazed out the ambulance window. "Oh," he replied, "I'd say about 50, maybe 55."
