Pay and productivity, it is generally assumed, should be related. But the relationship seems to weaken 【C1】______people get older.
Mental ability declines with age. That is the same for the brainy and the dim—and not【C2】______for humans: it is measurable even for fruit flies. 【C3】______minds that keep lively will suffer less than the lazy. In general, the more education you have, the more productive your old 【C4】______will be.
