From good friends to bad co-workers, our relations can affect our stress more than jobs and money. A new study suggests that the people around us can affect how long we live. Researchers focused on the effect that people called "hasslers" had on us. A hassler is someone annoying who hassles us. A researcher said, "having more hasslers is associated with accelerated biological aging…and how much wear and tear [people] have on their body".

Researchers questioned people about hasslers. Around one third of the participants knew at least one hassler. About 10 per cent had at least two hasslers. Each additional hassler was linked with a 1.5 per cent faster pace of aging. The researcher highlighted the negative effects of accumulated stress from hasslers, saying: "When you experience that chronically, over and over again, it has this long-term effect on the body."
