A new study has suggested that ageing changes people's sense of humour.
The study at University of Akron found that TV sitcoms in which characters make jokes at someone else's expense are no laughing matter for older adults.
Researchers, who studied how young, middle-aged and older adults reacted to so-called "aggressive humor," the kind that is a staple on shows like 'The Office,' found that young and middle-aged adults considered aggressive humor to be funny while older adults did not.
The older adults preferred "affiliative humor," in which a number of characters share and navigate an awkward situation.
The study is published in the journal Psychology and Aging.
