Do you know that the laughter could kill you? I am used to listening to 6 minutes English on BBC learning English as a source of new vocaburary and authentic listening practice. The last topic on that website was about laughter and how it may kill you. The explanation for this assumption ( quess ? ) was made by neuroscientist. She/he said that the diaphragm when we are laughing squeze the air out from our lung and it does not want to let us breath in. Also ( as well) I had learned british expression like 'to laugh your head off' that means laugh very loudly for a long time. There also the word 'guffaw' that means loud laugh and the opposite of that is chuckle. On the other hand the laughing could be as a natural painkiller because when someone is laughing the body release hormones which reduce pain feeling. I tend to believe in that theory that the laugh help us to reduce the stress and the pain and it is good for us. Please, check my note!
