而在富足的环境中，那些较弱的子细胞死得较少，那些拥有新细胞成分的子细胞生长、分割的更迅速。
In richer places, fewer runts died, and the daughters with shiny, new bits grew and divided very rapidly indeed.
后者的选择，子细胞即使不年轻，也有能力去避免衰老。因为没有一个子细胞是比它的母细胞更易老的。
The latter choice brings, if not eternal youth, then an equal pressure to avoid ageing, since neither daughter is more prone to death than the mother had been.
这是因为那些非对称分个所得子细胞中的弱者有可能在繁殖之前就死亡，这样就浪费了他们所吸收的食物。
That was because the runts tended to die before they could reproduce, thus wasting the food that they had already eaten.
在这一理论世界中，一个细菌能够“选择”死亡策略，它可以将所有老旧的细胞成分分配给一个没有前景的子细胞，并将所有希望寄托在另一个子细胞上，并将新细胞成分分配给它。
In this world, a bacterium can "choose" a mortal strategy, dumping all its old components into one daughter with limited prospects, and betting most of its future-and all of its new bits-on the other.
