The researchers gave 107 married couples voodoo dolls and pins for 21 days. They were told to place as many pins in the doll as needed each night depending on how angry they were with their spouse. They also blasted each other with noises through headphones while completing assigned taskes. Their blood glucose levels were monitored.
It appears that the lower your blood sugar, the more hostile and cranky you are. Others are more irritating to you and you are more irritating to others. So if you and your spouse are getting on each other’s nerves, try eating some food.
