Heart disease is the number one killer of women in America. In addition to keeping your cholesterol and blood pressure at normal levels, you can do many other things to keep your heart healthy. For example, keep up with friends on Facebook, host potluck dinners or just hang out with a friend to watch a movie. The Cleveland Clinic research suggests that nurturing a couple of solid friendships can cut your risk of heart disease by 40 percent and add 12 years to your life -- the same health boost that you’d get from eating an amazing diet! Having great friends to chat with and rely on keeps your blood pressure as many as 20 points lower, even during life’s most stressful and trying times, the study authors say. You only need a few minutes a day to send a newsy e-mail, have a quick chat during your lunch break or invite a pal to join you for your walk, to give you the protective perks of friendship, no matter how hectic your schedule!
