A: Your neighbor

HOW YOUR NEIGHBORS AFFECT YOUR HEART ATTACK RISK: You can choose your house, but you can’t choose who lives next door. New data indicates that if you can’t stand your neighbors, you may have an increased risk of having a heart attack. Researchers gave over five thousand adults over age 50 a survey about where they lived. Four years later, they found that 148 of the subjects had suffered heart attacks, and that those people had said the most negative things on the survey about where they lived. Those who lived in the friendliest neighborhoods reduced their heart attack risk by almost 70 percent. But why? It may be because good neighbors check up on each other and notice health issues, or because those who are happier where they live are overall less stressed. (Fox)
