1 . Is there a way to turn back the aging process in people? For centuries, people have been looking for a “fountain of youth.” The idea is that if you find a magical fountain, and drink its water, you will not age.

Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears that the answer may be called the hypothalamus, which is part of your brain. It controls important body activities, including growth, the way we process food and so on. Researchers found that hypothalamus neural stem cells (干细胞) also influence how fast aging takes place.

Dongsheng Cai was the leading researcher in a study on aging in mice. He and his team reported their findings. “when the hypothalamus starts aging, particularly the loss of hypothalamus stem cells, so does the body.” he said.

Using this information, the researchers began trying to activate (激活) the hypothalamus in laboratory mice. The results show that the treatment slowed aging in the animals. “When we injected the hypothalamus stem cells to the middle-aged mice, the mice aged slowly and they could also live longer.”

But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings. If so, they say the findings could lead to new ways to help doctors identify and treat age-related health problems.

3 . Eudaimonia is an Ancient Greek word, particularly stressed by the philosophers Plato and Aristotle, which deserves far more attention than it has because it corrects the shortfalls (缺失)in one of the most central, but troubling words in our modem language: happiness.

When we nowadays try to clearly express the purpose of our lives,it is the word “happiness” that we commonly turn to. We tell ourselves and others that the most important principle for our jobs, our relationships and the conduct of our day-to-day lives is the pursuit of happiness. It sounds like an innocent enough idea, but too much reliance on the term means that we frequently unfairly tend to quit or, at least, heavily question a great many challenging but worthwhile situations. The Ancient Greeks did not believe that the purpose of life was to be happy; they proposed that it was to achieve Eudaimonia, a word which has been best translated as “fulfilment”.

What distinguishes happiness from fulfilment is pain. It is very possible to be fulfilled and—at the same time—under pressure, suffering physically or mentally, overburdened and, quite frequently, in an irritable (易怒的)mood. This is a slight psychological difference that is hard for the word “happiness” to capture, for it’s tricky to speak of being happy yet unhappy, or happy yet suffering. However, such a combination is readily accommodated within the respected and noble-sounding idea of Eudaimonia.

The word encourages us to trust that many of life’s most worthwhile projects will sometimes be in conflict with contentment, and yet will be worth pursuing. Properly exploring our professional talents, managing a household, keeping a relationship going, creating a new business venture or engaging in politics... none of these goals are likely to leave us cheerful and grinning on a daily basis. They will, in fact, involve us in all manner of challenges that will deeply exhaust and weaken us, provoke (激怒)and wound us. And yet we will perhaps, at the end of our lives, still feel that the tasks were worth undertaking. Through them, we’ll have achieved something deeper and more interesting than happiness.

With the word Eudaimonia in mind, we can stop imagining that we are aiming for a pain-free existence—and then blaming ourselves unfairly for being in a bad mood. We’ll know that we are trying to do something far more important than smile all the time: we're striving to do justice to our full human potential.
