    Another thing an astronaut has to learn about is eating in space．Food is weightless, just as men are.

    Food for space has to be packed in special ways．Some of it goes into tubes that a man can squeeze into his mouth．Bite-sized cookies are packed in plastic.

    There is a good reason for covering each bite．The plastic keeps pieces of food from traveling in the spaceship．On the earth very small pieces of food would simply fall to the floor．But gravity doesn't pull them to the floor when they are out of the plastic in a spaceship．They move here and there and can get into a man's eyes or into the spaceship's instruments．If any of the instruments is blocked, the astronauts may have trouble getting safely home.

    As astronauts travel on longer space trips, they must take time to sleep．An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat．But be careful he must put his hands under the belt when he goes to sleep．This is because he is really afraid that he might touch one of controls that isn't supposed to be touched until later.

    Ever wondered whether punishment actually makes people cooperate (合作)? A team of scientists created an experiment to figure it out and the results were pretty unexpected.

    To understand what they found, you have to know why these scientists were studying punishment. They were trying to figure out why people cooperate when it's often so easy to profit at others expense. Why don't friends steal from each other? Why do parents bother to feed their children? If the answer to these questions is obvious to you, congratulations, you are ahead of scientists. They're still trying to figure it out.

    In this experiment, researchers had 225 Chinese students play a game, where if the students cooperated, they'd all get a number of points. But if one defected (变节) and everyone else cooperated, the defector would get a lot of points, and the cooperators would lose out. This game represents a lot of real life situations where you struggle with a decision: work together and do OK, or run off with the rewards, ruining everybody else's day.

    This is actually a pretty ordinary economic experiment. But the researchers added two changes to see if they could mimic(糢拟)the real world better. Change one: some students played many rounds together, so they'd learn who they could trust. Change two: people could punish each other, sacrificing a point or two to destroy another player's score.

    In the end, the researchers found that playing multiple rounds made people cooperate more, which definitely mimics human society. But the whole punishment thing led to a surprise: punishing didn't actually make people cooperate more. In fact, it made them cooperate less.

    So the scientists still don't know why people cooperate, though it looks like it has more to do with groups sticking together than it does with punishment.

When I grow up

    In kindergarten, my class was asked to draw pictures, showing what we wanted to be when we grew up. Our drawings were expected to display our dream occupations. I remember pictures of ballerinas dancing, firefighters putting out a blaze, and astronauts leaping across the moon.

    My picture showed a figure with brown hair holding a box of orange juice beside a counter. Underneath was my handwriting: "When I grow up, I want to work at Market Basket because it would be fun to swipe (刷) orange juice across the scanner." Out of everything, my five­year­old self wished to work at the local grocery store.

    When we are young, questions of what we want to be when we grow up are common. Yet we are not expected to respond with an answer that is likely to come true. However, when we become teens, we are asked the very same questions twice as often. The difference is, now we are supposed to answer with confidence.

    Teens are expected to know exactly what we want to be and how we are going to achieve that goal. However, not all of us can be so sure. Even though I am in high school, I cannot answer with certainty. But I don't consider that a bad thing. How am I supposed to know what I will want to spend my time doing at age 40?

    When I think about the future, I definitely don't see myself working at Market Basket, but in reality, if that was what would make me happy, I would do it. So, the next time someone asks me what I want to be when I grow up, I will simply say "happy".

    Happiness is a destination for everyone. We may want to walk different paths in life, but we all want to be happy wherever we end up. Choose your path, but don't worry too much about choosing wisely. Make a mistake or two and try new things. But always remember, if you're not happy, you're not at the end of your journey yet.
