     How can we all get more laughter into our lives? Here is what the experts suggest: 

     1_____. Nancy Alguire, a teacher in Clifton Park, N.Y., was once painfully shy and had a hard time

laughing. Then she married a circus clown (小丑). "I became interested in the clowns," she recalls "One

day, I put on a costume and paint my face. That afternoon my whole life changed. I leamed to laugh and

enjoy life in a way I had never done before." 2_____ To this day, she still makes it a rule to be with people

who enjoy life and laughing. 

     3_____ It doesn't take you too much time and can be easy. Collect favorite cartoons and jokes. Also,

keep a paper for writing down humor you find in everyday life. "Good ideas come and go fast, you have

to capture them quickly or they are gone," says Virginia Tooper.

     Laugh when you need it most "4_____" says comedian Bill Cosby. "And once you find laughter, no

matter how painful your situation might be, you can survive it," he insists.

     Gray Alan, a sociology professor at the University of Minnesota, claims that laughter is a skill we can

all gain-because it comes naturally. 5_____ Just remember: we are just here for a period, so get a few laughs.
