Travel should be about where you are going—not worrying about whether your body can keep up once you get there. But as we get older, a vacation can place surprisingly high demands on the body. Airports may require long walks between terminals. European vacations can mean cobblestone streets, stairs, hills, and hours of sightseeing. Cruises may involve ramps and moving surfaces. Golf trips can combine long flights with several consecutive days of activity. Even getting your suitcase into the car or lifting a carry-on into an overhead compartment requires strength, balance, mobility, and coord`ination.
