the power of smile

نوع خنده تعیین کننده طول عمر شماست

(psychological science)منبع            

پژوهشگران اخیرا از این مسئله که خندیدن و طول عمر با هم در ارتباط هستند فراتر رفته و به این نتیجه رسیده اند که نوع خنده در هر فرد با افزایش طول عمر وی رابطه مستقیم دارد.
به گزارش مجله علوم روانی ، پژوهشگران با بررسی تصاویر مربوط به 230 ورزشکار مشهور که هم اکنون در قید حیات نیستند نحوه خندیدن این افراد را به سه بخش لبخندهای جزئی (کوچک)، خندیدن میانه (متوسط) و قهقهه (در هنگام خندیدن) تقسیم کرده اند.

بنابر نتایج این پژوهش کسانی که در زمره سومین گروه قرار گرفته اند از دو گروه دیگر بیشتر عمر کرده اند.

بر اساس این پژوهش، میانگین طول عمر افراد دارای خنده های کوچک تنها به 45 سال رسیده است. در حالی که این میانگین در افراد دارای خنده های متوسط 72.5 سال و در گروه قهقهه زنان به 79.9 سال (نزدیک به دو برابر گروه اول) رسیده است

Smile your way to a long life

People who smile a lot are usually happier, have more stable personalities, more stable marriages, better cognitive skills and better interpersonal skills, according to research. Science has just uncovered another benefit of a happy face. People who have big smiles live longer.

Researchers at Wayne State University used information from the Baseball Register to look a photos of 230 players who debuted in professional baseball before 1950. The players' photos were enlarged and a rating of their smile intensity was made (big smile, no smile, partial smile). The players' smile ratings were compared with data from deaths that occurred 2006 and 2009. The researchers then corrected their analysis to account for other factors associated with longevity, such as body mass index, career length, career precocity and college attendance.

For those players who had died, the researchers found longevity ranged from an average of 72.9 years for players with no smiles (63 players), to 75 years for players with partial smiles (64 players) to 79.9 years for players with big smiles (23 players).

This isn't a bunch of psycho-hooey, the authors said. Smiles reflect positive emotion. Positive emotion has been linked to both physical and mental well-being. They added a caveat to their study, noting: "The data source provided no information as to whether expressions were spontaneous or in response to a photographer's request to smile." Still, big smiles are more likely to reflect true happiness than partial smiles.

What I'm wondering is, did they account for each team's winning records? Maybe the non-smilers were thinking about batting averages.

The study is published in the journal Psychological Science.
