Laughter is the sound that you make when you are extremely happy or something amuses you, and in many cases you may not be able to repress the impulse when something gives you great joy. Laughter quotes can be found that are funny or serious, depending on what you are looking for and where you look. Laughter can be very effective at lifting your mood and spirits, and it has been proven to help you stay healthier over time because it provokes a positive reaction in the body. Comedians try to elicit laughter from the audience, and they make a career out of amusing people. Sometimes you may feel an urge to laugh for no reason at all, and that is okay because your inner joy is bursting through.
