This is the point I wanted to bring up. As a pack-a-day smoker for 10 years, I got up from my desk for 10 minutes every 1.5 hours to smoke a cigarette. Later, as a non-smoker, a health-conscious manager told me he wanted me to get up from my desk once an hour to take a five-minute walk around the building for my health. Regular breaks during the day are better for your health than vacation days; although, both are good for your health.
