Dr. Coyne and his team videotaped the arguments that couples had at home and found that heart patients who were negative with their mates were nearly twice as likely to die within four years as were those who interacted less negatively.
Dr Coyne ja tema meeskond filmisid abielupaaride kodutülisid ja leidsid, et südamehaiged, kes ei saanud oma kaasaga hästi läbi, surid peaaegu kaks korda suurema tõenäosusega umbes nelja aasta jooksul kui need, kes said oma kaasaga paremini läbi.
