I just discovered a new reason to love the laugh lines and creases around my eyes: They may be a sign that I will enjoy a long life.

According to recently published research study, people who have big smiles in which also the corner of their eyes move live longer.

The way, how the study was done, may seem a bit unusual: Researchers at the Wayne State University in Michigan categorized 230 pictures of players from the 1952 Baseball register based on smile intensity: big smile, no smile, partial smile. They then compared the three categories with data from deaths and accounted for other factors that are related to longevity, such as body mass index or education. At the time of the study 184 of the 230 players had died.

The researchers found that players with a big smile lived in average 7 years longer as players who didn’t smile on their pictures. (79.9 years for big smiles versus 72.9 for no-smiles).

So – smile a lot and you live longer? Seriously?

The researchers say YES and offer an explanation: Our facial expressions reflect our emotions. We smile to express positive emotions. Also other studies have proven that positive emotions are related to better mental and physical health. People who smile often are more likely to have stable personalities and marriages, and also better relationships with other people.

An Australian/ New Zealand study about sleep in seven year old school kids found a link between too little sleep and obesity. The 519 children in the study slept an average of 10 hours per night. Those, who got less than 9 hours of sleep, were significantly more likely than the others to be overweight or obese. They were also at a higher risk for mood swings. The study is published in the Journal Sleep. (www.sleepjournal.org

Another study published several months ago found a similar link between sleep duration and body weight for adults. It seems that more time being awake translates to more time spent eating.

So, for those of us with a New Year resolution to sleep more, there is a new pro argument: sleep instead of diet. Works for me!
