If you don’t have a college degree, you’re at greater risk of developing memory problems or even Alzheimer’s (老年痴呆). Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive（认知的） advantage over those less educated in middle and old age.
Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures.
“The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long,” said lead author Margie Lachman, a psychologist. She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile (敏捷地).
But education early in adulthood does not appear to be the only route to maintain your memory. The study found that intellectual activities undertaken regularly made a difference. “Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education,” said Lachman.
The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with an average age of 56 years. Almost 40 percent of the participants had at least a 4-year college degree. The researchers evaluated how the participants performed in two cognitive areas, verbal (言语的)memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a series of tests, including tests of verbal fluency, word recall, and backward counting.
As expected, those with higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman.
“The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines,” said Lachman. “Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity (可塑性), and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle.”

I was walking along the main street of a small seaside town in the north of England looking for somewhere to make a phone call. My car had broken down outside the town and I wanted to contact the AA Company. Low grey clouds were gathering across the sky and there was a cold damp wind blowing off the sea which nearly threw me off my feet every time I crossed one of the side streets. It had rained in the night and water was dripping from the bare trees that lined the street. I was glad that I was wearing a thick coat.
There was no sign of a call box, nor was there anyone at that early hour whom I could ask. I had thought I might find a shop open selling the Sunday papers or a milkman doing his rounds, but the town was completely dead. The only living thing I saw was a thin frightened cat outside a small restaurant.
Then suddenly I found what I was looking for. There was a small post office, and almost hidden from sight in a dark narrow street. Next to it was the town’s only public call box, which badly needed a coat of paint. I hurried forward, but stopped in astonishment when I saw through the dirty glass that there was a man inside. He was fat, and was wearing a cheap blue plastic raincoat. I could not see his face and he didn’t raise his head at the sound of my footsteps.
Carefully, I remained standing a few feet away and lit a cigarette to wait for my turn. It was when I threw the dead match on the ground that I noticed something bright red trickling from under the box call door

Certainly dustmen prefer to be known as "Reuse Collection and Disposal Officers". You may think that this is rather 36 , and it is better to call a spade a spade.
