Will Your Marriage Last? Check Your Facebook Photos

Your Facebook photos (and your spouse's!) may say more about your future than you think. Recent research suggests that the more intensely you're smiling in photos (and there is a scientific way to measure smile intensity), the less likely you are to get divorced. Researchers first looked at yearbook photos, then at a range of photos throughout people's lives (even reaching back to age 10) and found the same link.

There's no heavy-duty neuroscience behind the association yet, but researchers suspect that this "positive emotionality," as they call it, leads people to be more open to social relationships, seek environments more conducive to happy marriages, and be better able to "undo" negative emotions. Feeling a little down or disconnected? Try these five easy steps to rediscovering the joy in your day-to-day life.

So what does this have to do with your health? Well, there's good evidence that divorce can mess with your health. People who've been divorced have more chronic health conditions and more mobility limitations, and they say their health is worse than continuously married people do. Plus, they have more symptoms of depression. Of course, an unhappy marriage can bring down your health, too. Best thing is to get it right the first time or to work hard at the marriage you have in order to make it the best you can. Good health isn't just about the food you eat; being emotionally well-fed is essential, too. Has time together left you both a few pounds heavier? Here are a few ways to tackle weight loss as a team.
