Have you ever wondered which gender laughs more? Do we usually laugh because something is funny? Robert Provine, author of Laughter: A Scientific Investigation, can answer these questions. Provine is a professor of neuroscience at the University of Maryland, Baltimore County, and the first researcher to conduct a full-scale investigation of laughter, taking what is a seemingly lightweight topic into the realm of serious science.

Over a span of ten years, Provine and his research assistants hit the malls and streets to document over 2,000 cases of naturally occurring laughter. From their many observations, they compiled some fascinating data about laughter, including the these 10 fun facts:

    • Laughter is an instinctive behavior, produced and recognized by people of all cultures.
    • Most laughter is not about humor, it’s about relationships between people. We are 30 more times likely to laugh in a social situation than when we are alone (without the presence of t.v., books, radio).
    • Laughter usually follows comments in conversation rather than intentional jokes.
    • The speaker tends to laugh more than the audience.
    • In groups, women laugh more than men. Women also laugh more at men more than men laugh at women.
    • Laughter tends to occur in short bursts of vowel-like sounds such as “ha-ha,” “ho-ho,” or “he-he,” which are repeated every fifth of a second.
    • Most people can’t laugh on command. Laughter is not something we produce consciously.
    • Laughter is contagious. The sounds of laughter often trigger laughter. The Tanganyikan laughter epidemic, for example, immobilized an entire school district during 1962.
    • Laughter is believed to have its origins in rough and tumble play, evolving from the panting behavior of our primate ancestors (when tickled, chimpanzees and gorillas pant).
    • Laughter usually doesn’t interrupt a sentence structure of speech. We really only laugh during the pauses we make for coughing or breathing.

    I’d rather laugh than frown or cry anyday. On a down day just tell a joke to a friend or find some good ones on the internet. Laughing is positive. You know what they say…A laugh a day keeps the wrinkle’s away….lol !

  • shari

    Hey Catherine. I’m with you. Better to laugh. And actually, the more wrinkles you have the better . . usually they mean you do a lot of smiling!

    You’ve got to check out the LOL Rollover Pets. They crack me up!

  • What is the phenomenon called that makes my 3 sisters and I burst into giggles whenever we’re supposed to be serious (like when my grandfather prays for 5 minutes on holidays) (Oh- btw we’re all grown women!)

  • shari

    This is surely the same phenomenon that my sister and I have fallen prey to. I love that laughter is contagious, especially among grown women! Thanks for your comment!

  • shari

    Ha! And yes, it does sound like a terrific read! Who knew there was so much science behind laughter?
    Thanks for reading!
