Have I told you about my friend Marie? She goes against every Las Vegas stereotype. She's incredibly fit and healthy, friendly, and active in her community. Here she is teaching a water aerobics class. Did I mention she's 80 years old? Prime View ran a story on her, "Marie McDonald: Making a splash water instructor dives head-first into 2nd career." She also has a book on physical fitness coming out soon (full disclosure: my mom edited it).
