A quarter of the people infected with a cold virus don't get sick. What's so different about these folks?

When it comes to colds, being young is no advantage: Teenagers catch twice as many as people over fifty.

It's strange but true: If you want to tamp down cold symptoms, "boosting" your immune system is actually the last thing you want to do!

The ways colds spread may surprise you. You're probably less likely to get a cold from kissing or getting sneezed on, than you are from a simple handshake.

Some cold viruses may be capable of triggering not just colds but corpulence-not just fevers but fat!

Social butterflies get off easy: People with big, diverse social networks actually get fewer colds than those with limited social circles.

Believe it or not, colds can kill.

You're right: Children do have runnier noses-and for good reason.

When you have a cold, TLC may be the best medicine. Studies show simple empathy may be as effective as potent drugs in treating colds, cutting short their duration by a whole day. That's more than over-the-counter medications can claim!
