Many people under age 50 get winded even thinking about a game of tennis or 18 holes of golf, but for many seniors, it's just par for the course. It is a proven law of physics that a body in motion stays in motion and a body at rest stays at rest, so it is a little easier for lifelong athletes to hit the courts and walk a course as seniors [source: NASA]. However, playing golf with the help of a cart and taking a look at newer versions of ball games like Pickleball make playing ball more accessible at all ages and fitness levels. One warning from the "initiated," though: Golf and competitive ballgames can be extremely addicting!
A slower paced, but no less enjoyable and social, option is bocce, or boccie, ball. Once it was best known in the United States as the pastime of older Italians in cities and retirement destinations like Florida, but bocce ball has a history dating back to ancient times and is played by seniors throughout the world at the amateur and competitive level [source: Encyclopaedia Britannica].
