纪录片《轻松活过101岁》 第10期 撒丁岛上的超健康家族

There are a great number of last names in Sardinia - more than 30,000,

撒丁岛上有许多姓氏，超过30000个，

but not many last names for the centenarians we have certified¹.

但是没有多少姓氏被证明有百岁老人。

Among these, there are some last names that show a fairly consistent percentage of centenarians.

这其中，有一些姓氏显示出有相当比例的百岁老人。

It's these ultra-healthy families like the Vaccas that make Sardinia unique.

象Vaccas这样的超健康家族让撒丁岛变得很独特。

The challenge for Professor Deiana is to find out why.

Deiana教授面临的挑战是找到其中的原因。

Maria's nephew, Alessandro Vacca,

Maria的侄子，Alessandro Vacca

can trace his family history in Ovodda back over several generations.

可以将他的家族史上溯几代人。

For hundreds of years, the Vaccas have lived in relative isolation² from the rest of the world,

几百年来，Vaccas的生活与世隔绝，

marrying into almost every other family in the town.

与镇上几乎每一个其他家族都有通婚。

In fact, most people living in the town today are descended³ from only a few original settlers.

事实上，如今镇上生活的大多数人，只有少量是原定居者的后裔。

Marriage among relatives is not the rule, but there are some cases of this taking place.

姻亲不是规律，但是也是这里的个案。

From a genetic⁴ point of view, when this happens,

从遗传的角度来看，在这种情况下，

there's a higher probability of having genetic diseases

会有一个较高的遗传性疾病的概率，

but also of having positive results - like centenarians.

但是也有积极的成果——比如百岁老人。
