THERE'S something about your friends that you should know.
They often deliberately put themselves in situations that will make them suffer a seizure. Sometimes they even make each other have convulsions so strong that their stomach, chest and ribs throb with pain and they become unable to breathe or even speak.But what is really scary is that they’d love you to join in with their bizarre, masochistic behaviour. And often you do.Not that you know what you are doing to yourself, of course.
You are too caught up in the moment to notice that your pulse rate has doubled and your systolic blood pressure has sky-rocketed.You barely realise that respiratory spasms are tying your thoracic muscles in knots or that your vocal cords are so bombarded by conflicting signals, they can’t produce an intelligible sound.Endorphins are surging through your blood vessels, sending your organs into turmoil. But you don’t care – you feel great. You are having a laugh.
It’s a funny thing, laughter. Funny peculiar, I mean. We’re not the only species to do it. Chimpanzees like a good chuckle, especially if you tickle them. But they don’t make jokes at the expense of blonde chimps – that’s a singularly human trait. In fact, our species probably laughs more often and at more things than any other species on the planet.“A lot of scientists think humans learned to laugh as a way of bonding long before we started talking to one another,” says Professor Sophie Scott from the Institute of Cognitive Neuroscience at University College London. “Sharing a joke is a way for us‑to relieve tension and stress.”
