so that's a pretty long day. right? okay. so people who work 10 to 11 hours had a 45% increased risk of heart disease compared to people who just work a regular 8-hour day. if they worked more than 11 hours, on increased risk of 65% of heart disease. so obviously this tells you a little something that all that work may not be too good for you. that's why i give everyone permission, 5:00, get out. go home. >> how many do you know in any business that works an eight-hour day? >> it's tough. people are grateful to have jobs in this economy. >> they'll work however many hours it takes. is it just about the work that affects you? is it the stress? >> partly it is the stress. doctors know stress is bad for your heart, but part is also just a time thing. if you're spending 11 hours at work, how do you have time to make healthy meals? time to exercise? so that's also part of it. just a scheduling thing. >> i can relate to that. i try to exercise. i really do, but it's tough sometimes.
