As many people hit middle age, they often start to notice that their memory and mental clarity are not what they used to be. We suddenly can’t remember where we put the keys just a moment ago or an old acquaintance’s name. As the brain fades, we refer to these occurrences as "senior moments." While seemingly innocent, this loss of mental focus can potentially have a detrimental impact on our professional, social, and personal well-being.
Neuroscientists are increasingly showing that there’s actually a lot that can be done. It turns out that the brain needs exercise in much the same way our muscles do, and the right mental workouts can significantly improve our basic cognitive functions. Thinking is essentially a process of making neural connections in the brain. Because these connections are made through effort and practice, scientists believe that intelligence can expand and fluctuate according to mental effort.

A. They are nothing to be worried about.
B. They happen to each middle-aged person.
C. They mostly happen to the elders.
D. They are signs of declining memory.
