When I was young, I had an old neighbor named Dr. Gibbs. He didn't look like any doctor I'd ever known. He never shouted at us for playing in his yard. I remembered him as a neighbor who was nicer than anyone else in the neighborhood. When Dr. Gibbs was happy, he was planting trees. And his life's goal was to make it a forest.

    Dr. Gibbs had some interesting theories about planting. He talked about trees that weren't watered would grow deep roots in search of water. So he never watered his trees. He planted an oak (橡树) and, instead of watering it every morning, he beat it with the rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.

    Dr. Gibbs died a couple of years. Every now and then, I walk by his house and look at the trees that he planted twenty-five years ago. They're very strong now.

    I planted a couple of trees a few years later. I watered them regularly and took good care of them. Whenever a cold wind blows, they shake their leaves and branches.

    The funny thing about those trees of Dr. Gibbs was that difficulty seemed to help them in ways comfort and ease never could.

    My parents knew their wealth: each other, their six children, and their faith. They tried to live simple lives so that they could have time for what was most important.

    They didn't busy themselves buying a bigger house, because that would mean working harder to pay the monthly mortgage(按揭贷款), working overtime or taking a second job. Who would go running with me then? Who would read stories to me?

    They didn't burden themselves with buying an expensive car because that would mean worrying about installment(分期付款) bills. Besides, walking to the shopping centre every Saturday afternoon with me gave my dad his needed exercise, and made me feel so special.

    One of my heart's delights was seeing Dad and Mom in their bedroom at night, after our nightly family prayer. The lights were turned off, and I'd see the figure of my father seated on his old chair and Mom standing behind him, gently massaging his shoulders. I'd hear them talk about what happened during their day. Even as a child, I sensed their quiet pleasure in being together.

    My question today: Could they have done this rich practice each night and nourished(滋润) their marriage if they had been busy paying for expensive clothes for themselves or their kids, or if they had been worrying about monthly bills for new hi-tech equipment? I don't think so. And I've made a choice: I don't want that of life either.

    In 1971 a young man who grew up very poor was traveling across the country, trying to make a new start for himself. Along the way he had completely run out of（用光了...） money and was forced to spend the night in his car. This continued until one morning, after a week of sleeping in his car, he walked nervously into a restaurant and ordered a big breakfast.

    After eating his first good meal in weeks, he found himself lying to the waiter, telling him he had lost his wallet. The waiter, who was also the owner, walked behind the chair where the young man had been sitting. He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, “Son, you must have dropped this,”the owner said. The young man couldn't believe his luck! He quickly paid for the breakfast, left a tip, bought gas with the change, and headed West.

    On the way out of town, he began to understand what the owner did. Maybe nobody dropped the money at all.“Maybe that fellow just knew I was in trouble and he helped me in a way that didn't embarrass(使尴尬)me. So I just made a promise to help other people if I can.”

    Later, he worked very hard and became a rich man. Now he lives near Kansas City. Each year he gives away thousands of dollars. He is known as the “Secret Santa” because at Christmas time each year, he personally hands money out to those on the street and at restaurants. Last year, he gave more than $50,000 away in Kansas City.

    CHICAGO -- New research on vegetables and aging gives mothers another reason to say "I told you so." It is found that eating vegetables appears to help keep the brain young and may slow the mental decline（下降） sometimes associated with growing old.

    On measures of mental sharpness, older people who ate more than two servings of vegetables daily appeared about five years younger at the end of the six-year study than those who ate few or no vegetables.

    The research in almost 2,000 Chicago-area men and women doesn't prove that vegetables reduce mental decline, but it adds to mounting evidence pointing in that direction. The findings also echo（回应） previous research in women only.

    Green leafy vegetables including spinach（菠菜）, kale and collards （甘蓝） appeared to be the most beneficial. The researchers said that may be because they contain healthy amounts of vitamin E, an antioxidant（抗氧化剂） that is believed to help fight chemicals produced by the body that can damage cells.

    Vegetables generally contain more vitamin E than fruits, which were not linked with slowed mental decline in the study. Vegetables also are often eaten with healthy fats such as salad oils, which help the body absorb vitamin E and other antioxidants, said lead author Martha Clare Morris, a researcher at the Rush Institute for Healthy Aging at Chicago's Rush University Medical Center.

    The fats from healthy oils can help keep cholesterol（胆固醇）low and arteries （动脉）clear, which both contribute to brain health. The study was published in this week's issue of the journal Neurology and funded with grants from the National Institute on Aging.

    Important facts about ELIQUIS® (apixaban)

    This is a summary of important information that you need to know about ELIQUIS. Keep this document in a safe place, so you can refer to it before and during your treatment.

    Look out for the following signs as you read:

Do not stop taking ELIQUIS without talking to the doctor who prescribed (开处方) it to you.

    Talk to your healthcare team before any medical procedures. ELIQUIS may need to be stopped before surgery, or a medical or dental procedure. Your doctor will tell you when you should stop taking ELIQUIS and when you may start taking it again.

    Talk to your healthcare team about the following:

    Liver problems any other medical conditions if you have ever had bleeding problems.

    Tell your doctor if you are pregnant or breastfeeding, or planning to become pregnant or breastfeed. You and your doctor should decide whether you will take ELIQUIS or breastfeed. You should not do both.

    Tell your healthcare team about all of the medicines you are taking.

    On the banks of Tanzania's Lake Eyasi lives the world's last hunter-gatherer tribe (部落) — the Hadza. They don't grow food, raise animals or build houses. Instead they live a life unchanged for more than ten thousand years.

    Their world is one of complete freedom — something modern society can barely imagine and is unlikely to ever experience, let alone have the skills to stay alive. Text messages and phone calls don't exist. Nor do cars and electricity. No jobs, timetables, and social structures. No laws, taxes and unbelievably, no money — the closest thing to currency (交易) is the trade for a pair of shorts with a neighboring tribe.

    We spent our time with the Hadza hunting baboons (狒狒), a daily activity for the men. Their land is packed with sharp bushes, poisonous snakes and man-eating lions. But a successful hunting trip is the difference between eating or going hungry.

    The Hadza diet consists mainly of honey, fruit and meat. Men often hunt in pairs to shoot animals with bows and arrows. The Hadza show us how to track animals, from baboons to snakes to lions. They are hugely skilled with their handmade bows and arrows — we have a go and barely get the arrow to go three feet in front of us.

    The language of the Hadza is believed to be the oldest still-spoken language known to man. The Hadza don't have conflict, and have no memory of starvation. Their population never reaches numbers that cannot be supported through hunting or gathering. They never get from their land more than they need.

    Unlike modern-day office workers, the Hadza enjoy an extraordinary amount of free time. Their “work” — hunting for food — takes up around five hours of their day. They've been in such a state of peaceful existence for thousands of years.
