The results of a new study by researchers from the University of Kansas revealed that couples who laugh together and have their own jokes, stay longer than others.

In contrast, the researchers noted, couples who had vicious jokes about each other and their relationship were not able to stay together for an extended period of time.

The researchers explained that the jokes and laughter between them is a cornerstone of the strong relationship and understanding between them.

The researchers came to these findings by targeting more than 150,000 participants, and confirmed that couples who create jokes and a sense of humor together, called inside jokes, tend to stay together for an extended period of time.

However, the researchers warned couples not to cross some red lines in pranks and jokes, such as those targeting the partner’s family or partner, that would cause major problems and disputes.

Therefore, it is important for couples to know their limits in pranks, and not to belittle the partner.

While the researchers reported that couples should stop joking and making jokes if they cause sadness or anger for the partner, the goal is to laugh and not belittle the matter.
