Giving a mouse this drug, then, would kill cells which had reached their Hayflick limits while leaving other cells untouched.

让一只老鼠服下吃药，然后，就会杀死那些已经达到海佛烈克極限的细胞，而不杀害其它的细胞。

The Hayflick limit, as the upper bound is known (after Leonard Hayflick, the biologist who discovered it), is believed to be an anticancer mechanism.

由于存在分裂上限，（这个理论被海佛烈克发现），海佛烈克極限机制被认为能够防止体内细胞发展成为癌细胞。

It is not an elixir of life, for eventually the body will run out of cells, as more and more of them reach their Hayflick limits.

但这并不是生命的万灵药，因为随着越来越多的细胞达到海佛烈克極限，身体机能最终还是会耗尽细胞的数量。
