We eat in our cars, at our desks, on the go, and in front of the TV. We eat take-out, packaged and prepared meals. Why ? Because it fits our not-enough-time-in-the-day lifestyles. 1. Well, I’m certainly not the first one to think it—or say it—but we all need to slow down.
Consumer trends around the globe show that over the past three decades people are purchasing more prepared foods at the grocery and eating out more than ever before. It’s predicted that we’ll spend more at restaurants in the coming years. 2.However, we’re getting less healthy.
While debates can be seen indifferent media over the food industry’s contribution to our growing waistlines and our health problems, the bottom line is this: 3.We can choose to eat a fast-food lunch on the go. We can throw a frozen meal in the microwave and call it dinner. We can eat without thinking, in front of the tube, at our computers, and while driving a car.
4.Studies have shown meaningful links between family meals and kids’ mental and physical well-being. Eating sensibly doesn’t take much time or money, but it does require you to make a conscious decision to do so. Wrapped in endless work, appointments and social activities, we often fail to enjoy a relaxing meal with our families.
While it can be a challenge to always put healthy eating first, just do your best. Remember that the food you eat has a more significant impact on your health, weight and well-being than almost any other activity you do. 5. Every meal made at home—even just once or twice a week—is a step closer to a healthier body and as lower food lifestyle.
A. Our food matches our lives.
B. Treat it with the importance that it deserves, but start small.
C. We’re consuming an increasing number of calories.
D. Lunch is the biggest calorie intake when it comes to eating out.
E. Purchase food locally and skip as many packaged items as you can.
F. What we eat, where we eat and how we eat are all under our control.
G. We can devote an hour of the day to enjoying a meal with our families.
Senses That Work Together
When we think about how our senses work, we usually imagine them operating separately: you sniff a flower, and the smell is delivered uninterrupted from nose to brain. However, it’s more complex than that. Most evidence for cross-modal perception (知觉) comes from studies into sound and vision (视觉). But research that shows other senses crossing over is coming out all the time, and it seems that even sound and smell sometimes form an unlikely pairing.
When New York researchers, Daniel Wesson and Donald Wilson, tried to find out the truth about a “mysterious” area of the brain called the olfactory tubercle (嗅结节)，they had to deal with this fact. Originally, they only intended to measure how olfactory tubercle cells in mice responded to smell. But during testing, Wesson noticed that every time he put his coffee cup down with a clunk (哐啷声)，the mouse cells jumped in activity. In fact, the olfactory tubercle is well-placed to receive both smell and sound information from the outside world. Later they found that among separate cells, most responded to a smell but a significant number were also active when a sound was made. Some cells even behaved differently when smell and sound were presented together, by increasing or decreasing their activity.
Of course, mice aren’t people, so research team has been carrying out further experiments. They pulled together a group of people and gave them various drinks to smell. Participants were asked to sniff the drinks, and then match them to appropriate musical instruments and produce the notes at different levels. The results were interesting: piano was regularly paired with fruity fragrances; strong smells sounded like the instruments that are made of metal.
Further research found that listening to different sounds can change your perceptions. Studying taste this time, the team ordered some special toffee (太妃糖)and put together “soundscapes” corresponding to bitterness and sweetness. Participants tasted similar pieces of toffee while listening to each soundscape, and found the toffee more bitter or sweeter, depending on which soundtrack they were listening to.
Studies like this are helping scientists correctly describe our understanding of the senses, and how the brain combines them with its advantage. The consequences are worth considering. Could we see musicians work together with chefs to produce sound-improved food and drink? Will you be ordering a coffee with a soundtrack to bring out your favorite smell? Come to think of it, that could be one thing you hope coffee shop chains don’t get round to.

Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.
We experience this tiredness in two ways: as start-up fatigue (疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.
Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.
Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical order, never letting myself leave out a tough idea. And I always started the day’s work with the difficult task of essay-writing. Experience proved that the rule works.
Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can—then let the unconscious take over.
When planning Encyclopedia Britannica( 《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after day I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.
One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.
An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind proved correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.
Human beings, I believe, must try to succeed. Success, then, means never feeling tired.
