Like sheep that get lost nibbling away at the grass because they never look up, we often focus so much on ourselves and our problems that we get lost.

Laughter, and the broader category of humor, are key elements in helping us go on with our life after a loss.

Now, a recent study from cardiologists at the University of Maryland, has shown that laughter may have a beneficial effect on the heart.

In looking for humor, keep in mind this guideline: Sometimes it takes a little time to see the humor in your upsets; you may not find something to laugh about immediately.

Advertisers also know that humor can help bond us to their product.

No matter what has happened, you too have the power to enjoy yourself.

Humor expands our limited picture frame and gets us to see more than just our problem.
