Workers who leave the office at 5:00 pm sharp lead happier, healthier lives

There's something to be said for leaving the office at 5 p.m. sharp.

A new study finds those who leave work on time each day are happier and healthier than those who stay later.

A previous study found that people who worked more than 55 hours a week were 33 percent more likely to suffer a stroke compared to those who worked 40 hours per week.

The experts say that telling those you work with that you'll be leaving at 5 p.m. sets the right atmosphere, even if others tend to stay late.
