"Wimp Factor" at Work in Men's Illnesses?

NEW YORK -- Women laugh about "man flu," which somehow causes men to think they have a serious flu, when in fact, they have only a common cold. Women have long observed that some men have a tendency to complain a little more at the first sign of a sniffle, or even a slight headache.

And now, researchers in South Korea say there may be something to all that!

In the study, men under pressure at work were 74 percent more likely to take time off because of a cold, and men who lacked control over their jobs were 42 percent more likely to call in sick.

Women, the researchers found, didn't take more time off from work, partly because they have a more stoic response to sickness.

She discussed it with co-anchor Erica Hill:
