问题      Advancing age means losing your hair, your waistline and your memory, right? Dana Denis is just 40 years old, but  (21)______   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  (22)______   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  (23)______   you remember? Well, sort of. But as time goes by, we tend to blame age  (24)______   problems that are not necessarily age-related.
     "When a teenager can’t find her keys, she thinks it’s because she’s distracted or disorganized," says Paul Gold "A 70-year-old blames her  (25)______  ." In fact, the 70-year-old may have been  (26)______   things for decades.
     In healthy people, memory doesn’t worsen as  (27)______   as many of us think. "As we  (28)______   , the memory mechanism isn’t  (29)______  ," says psychologist Fergus Craik. "It’s just inefficient."

But, cautions Barry Gordon, "It’s not clear that less activity is  (33)______   . A beginning athlete is winded(气喘吁吁)more easily than a  (34)______   athlete. In the same way,  (35)______   the brain gets more skilled at a task, it expends less energy on it.
     There are  (36)______   you can take to compensate for normal slippage in your memory gears, though it  (37)______   effort. Margaret Sewell says: "We’re a quick-fix culture, but you have to  (38)______   to keep your brain  (39)______   shape. It’s like having a good body. You can’t go to the gym once a year  (40)______   expect to stay in top form."
