If humans have any hope of living forever, we should probably take a hint from the dozens of other animals on Earth that far outpace our measly 71 years.
如果人类想要永生，那我们应该在地球上的很多其他动物身上找找启示，它们活得可比我们这71年长多了。

One of the longest-lived of these animals is the Greenland shark, which researchers only recently discovered could survive for so long.
格林兰鲨就是这些最长寿动物中的一员，研究人员最近才发现它们可以活这么长。

On a 2017 expedition, researchers learned more fascinating details about the shark, including that it's heart rate is incredibly slow — only beating once every ten seconds.
