问题     Advancing age means losing your hair, your waistline and your memory, right? Dana Denis is just 40 years old, but【1】she’s worried about what she calls "my rolling mental blackouts." "I try to remember something and I just blank out," she says.
    You may【2】about these lapses, calling them "senior moments" or blaming "early Alzheimer’s(老年痴呆症)". Is it an inescapable fact that the older you get, the【3】you remember? Well, sort of. But as time goes by, we tend to blame age【4】problems that are not necessarily age-related.

    There are【16】you can take to compensate for normal slippage in your memory gears, though it【17】effort. Margaret Swell says: "We’re a quick-fix culture, but you have to【18】to keep your brain 【19】shape. It’s like having a good body. You can’t go to the gym once a year【20】expect to stay in top form."
