    People often talk about how difficult it is to keep a healthy lifestyle while on vacation. A cruise （船）is the perfect example--too much food and too little exercise.1.Then I realized that’s of taking such vacations, we would all be better off taking vacations that encourage healthy behavior. Things like hiking and cycling are not only healthy, but they're cheap! 2.－we couldn't afford to do such else!

Gerhard Strauss-Blasche and colleagues examined the links between vacation environment and recovery.   3. They filled out questionnaires within two weeks of returning from a short vacation. Post-vacation recovery was assessed by quantifying how closely subjects agreed with the statement "In comparison with the two weeks before vacation, I now feel mentally fitter, feel more balanced and relaxed, can concentrate better during work, feel physically fitter, and do my work more easily.”

4.?Physical activity during the trip was positively associated with post-vacation recovery scores. In other words, the more physically active people were during their vacation, the more likely they were to feel relaxed upon their return. 5..In fact, I wouldn't take this study too seriously. But I don't think it's surprising that people who engage in(参加）healthy behaviors during a vacation might feel better upon their return. So instead of looking at your vacation as a potential block to your healthy lifestyle, why not look at it as a chance to improve your healthy behaviors?
