The only thing I can think of is maybe using a `reduce` here instead of an each. Then you could get rid of the `oldestLivingFather` variable. 

```
    return _.reduce(livingFathers, function (oldestLivingFather, livingFather) {
        if (livingFather.age > oldestLivingFather.age) {
          return livingFather
        }
        return oldestLivingFather;
    }).name;
```
or something like that.
