The broader your grin and the deeper the creases around your eyes when you smile, the longer you are likely to live。

你在微笑的時(shí)候嘴咧的越大，眼周?chē)�的皺紋越深，你可能活的越久。

Broader grins and wrinkles around the eyes reflect an underlying positive outlook on life that translates into better long-term health, the researchers believe。

大大的笑容和眼周深深的皺紋反應(yīng)了你對(duì)生活潛在的態(tài)度，這種態(tài)度讓你過(guò)一個(gè)長(zhǎng)久健康的生活。

Experts studied 230 pictures of major league baseball players printed in the 1952 Baseball Register。

專(zhuān)家們從1952年的一些主要的棒球聯(lián)盟中研究了230名注冊(cè)棒球隊(duì)員的照片。

The researchers ranked each player according to whether they had no smile at all, a partial smile, where only the muscles around the mouth were involved, or a full-blown smile that featured a toothy grin, raised cheeks and creases around the eyes. The researchers then compared the photos with the life span of each player。

專(zhuān)家們按隊(duì)員們的笑容進(jìn)行等級(jí)分類(lèi)，分別是“一點(diǎn)都不笑”，“笑了一點(diǎn)兒”，“微笑時(shí)嘴部肌肉有抽動(dòng)”或是“笑的合不攏嘴”，以及“揚(yáng)起臉，眼睛都笑出了皺紋”等這幾個(gè)分類(lèi)。然后他們把這些照片與隊(duì)員們的壽命進(jìn)行了比較。

The results revealed that of the 184 players that had since died, those in the 'no smile' category had lived an average of 72.9 years。

結(jié)果顯示，在184名現(xiàn)已去世的隊(duì)員中，那些屬于在照片中“從不微笑”的人，他們的平均壽命是72.9歲。

The findings support another study which showed that being happy can reduce the risk of heart disease

這些證據(jù)同時(shí)也支撐了另一項(xiàng)研究，那就是保持快樂(lè)的心態(tài)會(huì)降低得心臟病的風(fēng)險(xiǎn)。
