A day without laughter is a day wasted
Some people, when hearing a joke, smile. A collection of 17 muscles around their mouth contorts and their eyes crease up.
Others laugh. They emit a series of short vowel-like notes, each around 75 milliseconds long, repeated at regular intervals of 210 milliseconds apart.
You don’t stop laughing because you grow old: You grow old because you stop laughing.
Laughter is a funny business. It’s part of human behaviour all over the world, irrespective of culture. It takes place whenever two or three people meet informally, when somebody else strokes our feet, when a four-month-old baby sees a familiar smiling face.
Laughter is the music of the heart.
Laughter makes us less stressed, lowers our blood pressure and reduces anxiety. It’s more common than sex, eating or singing. And yet it remains one of the least understood aspects
of human behaviour.
Laughing is good exercise. It’s like jogging on the inside.
