It spans(横跨) both sides of the Huangpu River, with 3.93 km² in Pudong and 1.35 km² in Puxi. There are five functional zones marked A, B, C, D and E. Each of them has different functions.

    The Healthy Habits Survey（调查）shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

1). How many times did you brush your teeth yesterday?

Finding：A full 33% of seniors brush their teeth only once a day.

Step：Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

2). How many times did you wash your hands or bathe yesterday?

Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.

Step：We touch our faces around 3, 000 times a day-often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

3). How often do you think about fighting germs?

Finding：Seniors are not fighting germs as well as they should.

Step：Be aware of germs. Do you know it is not your toilet but your kitchen sponge（海绵）that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    By trying to tickle(挠痒痒) rats and recording how their nerve cells respond, Shimpei Ishiyama and his adviser are discovering a mystery that has puzzled thinkers since Aristotle expected that humans, given their thin skin and unique ability to laugh, were the only ticklish animals.

    It turns out that Aristotle was wrong. In their study published on Thursday, Ishiyama and his adviser Michael Brecht found that rats squeaked and jumped with pleasure when tickled on their backs and bellies. These signs of joy changed according to their moods. And for the first time, they discovered a special group of nerve cells. These nerve cells made this feeling so powerful that it causes an individual being tickled to lose control.

    To make sure that he had indeed found a place in the brain where tickling was processed, Ishiyama then stimulated that area with electrical currents. The rats began to jump like rabbits and sing like birds.

    “It's truly ground-breaking,” said Jeffrey Burgdorf, a neuroscientist at Northwestern University who reviewed the paper. “It takes the study of emotion to a new level.”

    Burgdorf has played a central role in our understanding of animal tickling. He was part of a team that first noticed, in the late 1990s, that rats made special noises when they were experiencing social pleasure. Others had already noted that rats repeatedly made short and high sounds during meals. But the lab where Burgdorf worked noticed that they emitted similar sounds while playing. And so one day, the senior scientist in the lab said, “Let's go and tickle some rats.” They quickly found that those cries of pleasure doubled.

    “The authors have been very adventurous,” said Daniel O'Connor, a neuroscientist at Johns Hopkins University who studies touch. To him, that finding was very surprising.

    “Why does the world literally feel different when you are stressed out?” he said. “This is the first step towards answering that question. It gives us a way to approach it with experimental rigor(严谨).”

    Which country can you travel to in 2020 that will allow you to go for longer, enjoy a higher standard, and save more money? The following destinations offer accommodation, transportation, and food for less.

Kyrgyzstan, $25/day

    Kyrgyzstan is the choice for most travelers interested in trying out Central Asia, and most well-suited to travelers of all budgets. Food is cheap, so is getting around using the minibuses. You can find hostels and local home stays for less than $10. Meals cost $4 – $8 per day.

    Romania, $33/day

    If you are planning a European trip that's affordable and a little bit off the beaten path, Romania is perfect for you. Unlike other popular places, many charming towns here remain unknown to most foreigners. You can also take free walking tours in the numerous historical sites. Hostels run $10 – $15 per night, food is hearty and delicious, and the public transportation is reliable and affordable. Meals cost $10 – $15 per day.

    Arizona & Utah, $55/day

    For an American Southwest road trip, you'll spend an average of $110/day when you are solo. If you have just one other person, you'd be able to split the costs almost perfectly in half. If you have two other people along, take it down to one third and so on. The more the merrier.

    South Africa, $40/day

    Any hostels in South Africa are in beautiful settings and each has a unique personality, and affordable too. Food can get expensive. To save money, cook your own food. Grocery stores are plentiful and have reasonable prices. By at least cooking your own breakfast, you can save a lot of money. The best (and possibly cheapest) way to get around the country is to rent a car and share with 3 other people. Meals cost $12 – $15 per day.

Life Begins on Board Your Next Cruise(邮轮)

On a cruise, it's all about choices. And never about effort or annoyance. Simply step aboard and float away, as your grand accommodation takes you from port to port, country to country. Maybe you haven't been on a cruise yet. Let's see what it might look like.

Rise and shine

Everyone is a morning person on a cruise. Wake up to find yourself floating joyfully somewhere out on the horizon, between vast blue skies and rolling oceans. You've travelled far through the night, and each morning begins with a completely new and foreign destination calling from outside your window. What a way to start your day!

Breakfast of champions

Before the morning truly begins, spend some time relaxing on the top floor with a steaming cup of coffee and warm French pastries, taking in the unbelievable views and the fresh sea air. Or head to one of the many restaurants on the ground floor to find a rich meal fit for a king, then walk to the front of the ship and have some fresh fruit and American pancakes in the open-air market.

Ease into your day

Energize your morning with a yoga class, strengthening your body on the open-air board, palms stretched to the sea. Hit the gym for a refreshing workout or take a swim that will set you up for the day. If you are not so sporty, simply spend your morning sitting by the pool reading a book, perhaps losing yourself in the history, culture and legends of your next port of call.
